Ephesians 2:8-9.
WHO hath saved us, and called us with a holy calling, not according to our works, but according to His own purpose and grace.
II Timothy 1:9.
NOT by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and renewing of the Holy Ghost.
Titus 3:5.
VERILY, verily, I say unto you, He that entereth not by the door into the sheepfold, but climbeth up some other way, the same is a thief and a robber.
John 10:1.
Jesus Christ is the door as the next verse shows and he who tries to save himself in any other way is called a “thief” and a “robber.”
I AM the door: by me if any man enter in, he shall be saved, and shall go in and out, and find pasture.
John 10:9.
