We are saved THROUGH GRACEI'll reply to only one thing that you wrote: every Christian religion believes in salvation by works after we attain faith.
That is not the case. Salvation is a gift of God; there is no salvation by works after we attain faith. (Or even before).
Ephjesians 2:8-9, "For it is by grace you have been saved, through faith—and this is not from yourselves, it is the gift of God— not by works, so that no one can boast.
BY FAITH
That is salvation.
What keeps us saved?
Colossians 2:21-23
21And although you were formerly alienated and hostile in mind, engaged in evil deeds,
22yet He has now reconciled you in His fleshly body through death, in order to present you before Him holy and blameless and beyond reproach—
23if indeed you continue in the faith firmly established and steadfast, and not moved away from the hope of the gospel...
John 8:31
....IF you abide in my word...THEN you are truly disciples of Mine.
James 2:6
For as the body apart from the spirit is dead, so also faith apart from works is dead.
Matthew 7:21
“Not everyone who says to me, ‘Lord, Lord,’ will enter the kingdom of heaven, but the one who does the will of my Father who is in heaven.
