  • Is Jesus Really God?   ( View as PDF )
    The issue of the deity of Jesus Christ has been hotly debated for centuries. It was an Alexandrian theologian named Arius who popularized the view that the preincarnate Christ was a created being who was, both in Essence and in Person, distinct from God. His view came to be called “Arianism,” and was condemned by early church councils. It is one of the Christological positions that fall under the label of “unitarianism.”
  • Who, What, is God?     ( View as PDF )
    Of all the theological questions that evoked controversy in the ancient “universal church,” none was more hotly debated than the question “Who, and What, is God?” Today, the debate continues. Some claim that Jesus Christ is “very God of very God,” while others claim that He was an archangel in His preincarnate state, or that He didn’t preexist at all. Just what does the Bible say about this? Did Jesus preexist? Does He have a right to the names and titles of divinity? And what about the Holy Spirit? Does the Bible present the Spirit as the Third Person of a Trinity?

The Kingdom of God

  • How You Can Enter the Kingdom of God 
    What does God require of a person before granting him the gift of eternal life and assurance of entry into the Kingdom? Must the truly-converted Christian, through combining good “works” with his faith, reach a certain level of spiritual perfection before he is qualified for entry into the Kingdom?
  • Is the Kingdom of God Here, Now?    ( View as PDF )
    Jesus Christ came proclaiming the good news of the Kingdom of God. He said, “Repent, for the Kingdom of God is at hand.” He also said, “I will build my church, and the gates of hell shall not prevail against it.” Is the church and the Kingdom the same thing? Was the Kingdom of God inaugurated on the first Pentecost following the resurrection of Christ? Has Christ’s Kingdom continued to expand until the present? Or is the Kingdom yet to be established?

Jesus Christ

  • Christ Can Be Preached From the Old Testament! But HOW, If It Is “Done Away”?
    The famous eunuch from Ethiopia was reading from the scroll of Isaiah when Philip was sent to him. Within only a few hours, the eunuch asked to be baptized. He had learned about Christ from Philip’s explanation of Isaiah’s prophecies. How was this possible? Could the eunuch have received Christ as his Savior, and been saved by grace, through understanding what Isaiah wrote? Isn’t the Old Testament “done away”? Is the knowledge necessary for salvation to be found in the Old Testament? Read, in your own Bible, the astonishing truth!
  • The Seven Declarations of Jesus and Evidence of His Resurrection 
    Jesus came to earth to lay down His life, but He also said He would raise it up! Are we willing to follow in His steps? Do we want to follow Him? Jesus said, “Whoever serves me must follow me; and where I am, my servant also will be. My Father will honor the one who serves me” (John 12:26). “And If I go and prepare a place for you, I will come back and take you to be with me that you also may be where I am” (John 14:3).”
  • Why Christ Must Return    ( View as PDF )
    According to a group of respected biblical scholars, Jesus Christ never promised He would return to this earth. The Second Coming, they claim, is a myth—a promise put on the lips of Jesus by His followers. But if Jesus Christ does not return, our world is doomed—there remains no hope!
  • Jesus Christ IS Fulfilled Prophecy!    ( View as PDF )
    In today’s world, many do not recognize the plain prophetic statements foretelling the coming of Jesus the Christ as the suffering servant. They ignore the specific declaration of His Messiahship, how it was to be accomplished, and what it means for mankind. This eye-opening article will prove from prophecies of the Old Testament that Jesus Christ is indeed the promised Messiah and Savior, prophetically validating Him as the coming King of Kings and Lord of Lords!


  • The Ten Commandments 
    Written with the finger of God on tablets of stone, the commandments of the Decalogue are everlastingly binding on the creatures who bear God’s image. The Ten Commandments existed before Moses, formed the heart of the covenant law God gave to Israel, and were observed by Christ, the apostles, and the entire New Testament church. They are still in force today. They are for your neighbor—and they are for you!
  • The Book of Galatians (PDF)
    In his epistle to the churches of Galatia, the Apostle Paul sternly warns those who were turning away from the One who had called them in the grace of Christ to a different gospel. Just what is this “different gospel” Paul so sternly opposed?


  • Ten Facts You Should Know About Repentance   ( View as PDF )

  • What is Sin?    ( View as PDF )

  • Used of God (PDF)

  • Immortality: God’s Gift to the Saints 
    No question about it, the Bible clearly reveals that immortality is God’s gracious gift to His saints. But if immortality is a gift that is given only to the saints, why do millions believe that it is an inherent quality of the human soul? What does the Bible say about this subject?
  • The Assurance of Salvation    ( View as PDF )
    What does God require of a person before granting him the gift of eternal life and assurance of entry into the kingdom? Must the truly converted Christian, through combining good works” with his faith, reach a certain level of spiritual perfection before he is qualified for entry into the kingdom? When, precisely, can a person experience the joy of salvation, with full assurance that if he were to die tomorrow he would rise to meet Christ at His return, and live eternally in the Kingdom of God?
  • The Questions & Answers Book 
    Over the years we have received literally thousands of questions on various biblical topics from our readers and viewers. In the past, we have addressed many of these questions in our various periodicals. Unfortunately, those new to our program and literature usually do not have access to the many questions and answers we have published in past years. For this reason, we have compiled, edited, and revised a fair number of the questions and answers we have published, and are now presenting them in this volume.
  • The Questions & Answers Book, Volume 2 (PDF)
    The questions have continued to come in. Here is the second volume of our Q&A series.
  • Is Water Baptism Required For Salvation?
    Is baptism necessary for salvation? When should it be done? Should infants be baptized? Should one be re-baptized in later years if one feels his first baptism was invalid? Should the living be baptized for the dead? What is the form for baptism? Sprinkling, pouring, or immersion? Can you be saved if you are not baptized? Who should do the baptizing? What if you were baptized by a man in whom you have since lost faith? Should you be baptized again? Here, from the pages of your own Bible, is the plain truth about water baptism.
  • Man’s Awesome Destiny    ( View as PDF )
    Life, for most of us, is filled with heartaches, disappointments, grief, and even intense pain. Even the person who “wins” in the game of life—the one who is born into a happy family, gets the best education available, lands the most rewarding job, marries the right person, has a happy marriage and wonderful children—must eventually face the reality of death. One is left wondering: Is this all life has to offer? Is it worth it?
  • Once Saved–Always Saved?   ( View as PDF )
    Can a truly converted Christian ever lose his salvation? Many evangelical fundamentalists say it is impossible. A person can no more “work” his way out of salvation, they say, than he can “work” his way into salvation. But what does the Bible say?
  • What Does the Bible Say About Predestination and Election?
    Did God, before the foundation of the world was laid, unconditionally predetermine who would be saved and who would not? Has your ultimate destiny already been set? Is it true, as Calvinists claim, that the elect were not appointed on the basis of their faith, good works, character, or anything else God could see within them? What about the famous “Five Points of Calvinism”?
  • Does God Love the World Enough to Save It?
    “For God so loved the world He gave His only begotten Son…”—John 3:16, undoubtedly the most quoted verse in the Bible. But if God loves the world so much, why does He seem to be doing so little to save it?

Holy Days

  • Christ Our Passover
    During Israel’s final hours in Egypt, God instituted a festival to annually remind the Covenant People of their miraculous delivery from the house of bondage. But that ancient feast proved to be more than a memorial of the Exodus.
  • The Origins of Our Calendar
    Is the calendar that underpins God’s holy days sacred or secular? Is time holy?
  • The Miracle of Pentecost 
    Read, in your own Bible, of the miracles that took place on the first Pentecost after Christ’s resurrection—the miracle of Pentecost!
  • Who Changed the Sabbath to Sunday?   (View as PDF)
    There can be no doubt that Christ, His disciples, and the first-century Christians kept Saturday, the seventh-day Sabbath. Yet, today, most of the Christian professing world keeps Sunday, the first day of the week, calling it the Sabbath. Who made this change, and how did it occur?


  • The Church Of God In Prophecy
    Jesus Christ promised that He would build His church, and that “the gates of Hades shall not prevail against it” (Matthew 16:18). And indeed, Jesus did build His church.

  • The Seven Churches of the Apocalypse
    The book of Revelation, also known as “the Apocalypse,” is one of the most fascinating books of the New Testament. It is filled with prophetic imagery—multi-headed beasts, strange celestial creatures, spectacular cosmic disturbances, and loathsome plagues being “poured out” on sinning mankind. But Revelation is also a book of exhortation and encouragement for suffering saints, as well as a book of admonition and warning for Christians who have strayed from the path of life. The book is addressed “to the seven churches of Asia” (Revelation 1:4), but its message is for every generation of God’s people. It’s time we listen to the voice of the Revelator! “He who has an ear, let him hear what the Spirit says to the churches.”
  • Heresies: Ancient and Modern
    “For false christs and false prophets will rise and show great signs and wonders to deceive, if possible, even the elect” (Matthew 24:24).


  • Bound to Appreciate
    God designed marriage to be a wonderful and loving relationship. Yet, today’s divorce rate indicates that many are not experiencing marriage for all that God meant it to be. What’s wrong with today’s marriages? How can YOU have a happy marriage?


  • Evolution: Fact Or Fallacy?
    No one can deny that our complex universe is an astounding, majestic marvel. But how did it get here? Where did we come from? Does it really matter? Can it be, as so many contend, that this all just “happened” by some fortuitous cosmic accident? Or did it come about as the result of the careful design of an infinite God? Here are the facts you need to know!


  • Evidence of the End Times
    Are we living in the prophesied time of the end? How can we know for sure?
  • The Great Day of the Lord 
    In three short chapters the book of Joel takes us from an ancient locust plague to the eschatological day of the Lord. How can two events so far apart in time and so different in content be related?

  • The Restoration of Sodom (PDF)

  • What Does the Bible Say About the Antichrist? (PDF)
    In the Christian community today, there is much confusion surrounding the word “Antichrist.” What does the Bible really say about this term? Is it something to be concerned with today? Or is it simply a quotidian expression assigned to some looming prophetic end-time leader or political world condition out in the future?

Satan, Demons

  • The Devil, You Say?    ( View as PDF )
    Many modernists believe that Satan the Devil is not a literal, personal being, but merely a “literary device,” or imaginary figure that personifies evil in much the same way the sickle-bearing “Grim Reaper” personifies death. But Scripture declares that a very real—and personal—devil is active in the world today, and seeks to destroy those who keep the commandments of God and hold to the teaching of Jesus.
  • UFOs EXIST! But What ARE They?    ( View as PDF )
