2 Timothy 3:16-17
[16] All Scripture is breathed out by God and profitable for teaching, for reproof, for correction, and for training in righteousness, [17] that the man of God may be complete, equipped for every good work.
The Bible is composed of 66 books, written by about 40 writers, over a time period of about 1500 years, yet there is no contradiction. Let that sink in for a second. 66 different books written by approximately 40 different writers over a time period of about 1500 years, and there are no contradictions. That is evidence that it is God-breathed alone. Think about it. A TV show written by a handful of writers in a room together will contradict themselves on the show in later seasons. Movie sequels will contradict the prequels. Yet, the Bible has no contradictions and has been preserved for over 3500 years.
People will deny these facts saying the Bible is full of contradictions, but when you read the context of those so-called contradictions, you will find that there actually is none. They believed their hypothesis was true before they sought out to prove it true, this tainting their search and clouding their judgment.
Peter tells us that we need to be prepared to give a reason we believe the things we do. In other words, we need to know our Bible and be able to defend our beliefs when they are attacked or questioned by the unbeliever. We need to know the reason one says Judas hung himself and another says his insides spilled out. We need to know why one says Mary went to the tomb and another says Mary and others went to tomb. Why one says one genealogy and the other says another. We need to know our Bible and we need to always seek the LORD for understanding of His Word, so that we might be prepared for any questions to our faith.
The Bible is without flaw or contradiction, as it is the Word of God. Why? Because it has but one author, the LORD God Himself who gave man the words to write. If the LORD God gave us His Word, the least we can do is learn it and defend it.
Peace. Love. Go Forth and Learn To Defend.
