For those who deny Jesus as The Messiah, or His existence, there are plenty of factors that led them to the conclusion of denial. 1 Peter 3:15 says, "Always be ready to give an answer to every man that asketh you a reason of the hope that is in you with meekness and fear." God's Word is infallible, historically reliable, aligns with scientific discoveries, and is philosophically sound. For genuine seekers of truth, you will find it! Trust Him! I hope and pray I INSPIRE you to test His Word, and INSPIRE others to do the same.
