One reason Christians believe Jesus is the only way of salvation is because this is what Jesus claimed about Himself. He declared, "I am the way and the truth and the life. No one comes to the Father except through me" (John 14:6).
Why did He make such a startling claim? Was it out of pride or ego? Or was He mentally unbalanced, or even deliberately lying to trick people into following Him? No, none of those "reasons" stand up once you carefully examine Jesus' life and teachings. Why, then, did He say He was the only way to the Father? Simply this: He knew that He was the unique Son of God, sent by His Father into the world to save us from our sins.
You see, only one thing separates us from God and keeps us out of heaven—and that is our sin. This is why our greatest need is to have our sins forgiven and cleansed, for only then can we be reconciled to God and go to be with Him throughout eternity.
But how is this possible? No matter how good we are, we can never erase our own sins. Only God can do this—and that is what He did by sending Jesus Christ into the world for us. The Bible says, "For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life" (John 3:16). Don't turn your back on His love, but by a simple prayer of faith commit your life to Christ today.
