John 14:6, Jesus answered, “I am the way and the truth and the life. No one comes to the Father except through me.”
This video clip by Living Waters will answer all your doubts on Christianity and will show you that it is above all other religions. Mark Spence who features in the video clearly states that while all religions point towards a mystery or aura as God, Jesus plainly states that He is the way, the truth and the life.
Do we need more proof that Jesus is God Himself, then we can turn to the word of God- the Bible which has thousands of verses to tell us the truth.
