You have the Source of salvation in the text: "Look unto me, and be ye saved, all the ends of the earth: for I am God, and there is none else." [Isaiah 45:22] Doesn’t it seem strange that we have to emphasize "me"? Salvation is not in a church, not in any denomination, not in sacraments, not in ceremonies, not in rituals, not in works, not in reformation; salvation is in a Person—the Lord Jesus Christ. "Look unto me, and be ye saved."
My most difficult job as an evangelist is getting people to look to Christ alone for salvation. Some very sincere people look to Jesus and the baptistry. "It is not enough to look to Jesus," they say; "you must also be baptized."
Now everybody who gets saved ought to be baptized by immersion in a local church, but no one gets baptized to be saved. It is not looking to the baptistry; it is looking to Jesus.
I have been baptized, and I try to live right. But if I had to die right now and stand at Heaven’s gate and were asked, "Curtis, why should we let you in?" I would not say, "Because I lived right." I believe I would stand tall and say:
“My hope was built on nothing less
Than Jesus’ blood and righteousness;
I dared not trust the sweetest frame,
But wholly leaned on Jesus’ name.”
