Our salvation is based on grace through faith, and the evidence of our salvation comes from the deeds of our faith. It is not possible to be a Christian and not be carrying out His will in our lives.
"For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life. "For God did not send His Son into the world to condemn the world, but that the world through Him might be saved. "He who believes in Him is not condemned; but he who does not believe is condemned already, because he has not believed in the name of the only begotten Son of God. "And this is the condemnation, that the light has come into the world, and men loved darkness rather than light, because their deeds were evil. "For everyone practicing evil hates the light and does not come to the light, lest his deeds should be exposed. "But he who does the truth comes to the light, that his deeds may be clearly seen, that they have been done in God.
- John 3:16-21
For by grace you have been saved through faith, and that not of yourselves; it is the gift of God, not of works, lest anyone should boast. For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand that we should walk in them.
Ephesians 2:8-10
