Why Is Jesus the Only Way?
Any reasonable person, I would think, even without reference to the Scriptures, would surmise that if there is one God, and that human beings are natively lost, that one God, if He cared to redeem man, would stipulate one way of salvation, not multiple choices. But apart from the Scriptures that would be speculation; the answer must be derived from revelation. And the only claimant to ‘revelation’ that has any credibility as such is the Bible.
Here is what it teaches:
There is, according to the Scriptures, one true and living God—the God of the Bible. This God is our sovereign Creator, bountiful Sustainer and gracious Redeemer in Christ. On the other hand, sinful man is dead in trespasses and sins. (Ephesians 2.1) Man inherently deserves nothing.. “The wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord.” Romans 6.23
So, “there is one God and One mediator also between God and men, the man Christ Jesus, who gave Himself as a ransom for all. . .” 1 Timothy 2.5-6. The one true and living God made a way—one way—of salvation for a race of lost mankind who do not deserve it. It is His call and His alone. In His love He made a way for sinners to be forgiven and reconciled to Him. In His sovereignty and justice He said, Jesus is the way, the truth and life.” John 14.6. End of story.
