The Jehovah’s Witnesses base their salvation on their works, knocking on doors. "Salvation is by personal merit and good works, not by grace through faith".

Some defense: John 3:3-8, 16-18, 5:24, 20:31, Acts 2:21,4:12,15:11, 16:31, Romans 3:21-31, 4:2, 5:1, 8, 6:23, 10:9, 10:13, 11:6, 2 Corinthians 5:17, Galatians 2:15-21, Ephesians 1:13, 2:8-9, 1 Peter 1:1-4, 1 John 5:13.

FAITH ONLY:

John 3:16-18 "For God so love the world that He gave His only begotten Son, that whoever believes in Him should not perish, but have eternal life. For God did not send the Son into the world to judge the world, but that the world should be saved through Him. He who believes in Him is not judged; He who does not believe is judged already, because he has not believed in the name of the only begotten Son of God." NASB

GRACE ONLY:

Ephesians 2:8-9 "For by grace you have been saved through faith; and that not of yourselves, it is the gift of God; not as a result of works, that no man can boast."

THROUGH CHRIST ONLY:

Galations 3:10-13 "For as many are under the works of the Law are under a curse, for it is written, ‘Cursed is everyone who does not abide by all things written in the book of the Law to perform them’. Now that no one is justified by the Law before God is evident; for the righteous shall live by faith. However the Law is not of faith; on the contrary, ‘He who practices them shall live by them.’ Christ redeemed us from the curse of the Law, having become a curse for us-for it is written, Cursed is everyone who hangs on a tree." NASB
