I Am the Way, the Truth, and the Life. No one comes to the Father except by Me. (John 14:6)
Jesus did not say, “I am A way, A truth, and A life.” This is proven by His next words: “No one comes to the Father except by Me.” He could not have been more clear. Now, (pardon me as I borrow an argument from C.S. Lewis) either Jesus Christ was liar, totally insane, or He was telling the complete Truth about Himself. Thus, those who say He was a good man or prophet have no basis for their claim. He continually made claims that no sane person could make about himself unless He were actually the Son of God.
People object to Jesus as the only way to God because they say that this demands that only Christians can be saved. That is absolutely correct. But the fact is, God invites all people to come to Christ and become Christians. Christ as the only Way is a narrow Way, but God invites all to come that Way.
Jesus is the only Way to God because He alone is the only begotten Son of God become man – and He alone died for us and was raised. He alone is Lord of all. This is not merely a matter of theology nor does not cater to human demands. It is the Truth.
