Salvation isn't earned by man, It's about what our God, The Lord Jesus Christ has done for us as sinners. He gave his life and shed his blood so that we may be justified and redeemed in front of our God, The Father who judges all sinners with justice through his wraith and righteousness. Believing that Jesus is God (Trinity), having Faith in his redeeming sacrifice and Trusting in his resurrection and defeat of death are the core principles of the Gospel and is of which man is saved from eternal separation from God and damnation in Hell.

Search for yourself the word of God, Don't trust in man to save you from yourself and the wraith of God.
1 Corinthians 15 is a good place to start.
