Apologetics | Biblical Insights

My name is John Gandiello. I am a twelve-year United States Navy (enlisted) veteran and a retired Senior Software Engineer. More importantly, I am a born-again believer who came to saving faith in Jesus Christ as a sailor over fifty years ago. Although I never attended seminary, I have sat under the teaching of men like Dr. John Whitcomb and Dr. Wayne Grudem as well as a few good pastors over the years. For the most part, I am self-taught and have led several Bible studies. Some of my study notes are available under the BIBLE STUDIES menu. Finally, I am the author of the book, Know Your Theology - Understand Why You Believe What Your Believe, available on Amazon and the Barnes & Noble Online Bookstore.

Are You Truly Saved?

It is hard to be a Christian in this world. Jesus said, “If the world hates you, you know that it has hated Me before it hated you” (John 15:18). Our adversary, Satan, “prowls around like a roaring lion, seeking someone to devour” (1 Pet. 5:8).

What Do You Do About Jesus?

If the Bible is true and there is only one God, and this God came in the flesh in the person of Jesus to die for your sins, then what are you going to do about Him? Jesus said, “I am the way, and the truth, and the life; no one comes to the Father but through Me" (John 14:6).

Rampant Biblical Illiteracy

Am I alone in thinking that the majority of church goers today are Biblically illiterate and/or just plain ignorant? Is the church today neglecting sound doctrine for the sake of unity?
