But not everyone will be saved. Salvation is like receiving a gift. We're pretty experienced at that. It is a gift, nothing that you have ever done can earn you closeness to God. Jesus Christ died on the cross to take away our sins or we could never come close to God.
Salvation is like going through a door.
Shepherds in those days when they wanted to bed their sheep down for the night would herd their sheep into an enclosure made of stones or branches and then the shepherd would lay down across the opening and the shepherd would literally be the door. Jesus is the door of the kingdom you can't get in except through him. Salvation is like coming home. Do you remember the story of the prodigal son. He finally came to his senses.
