God's grace saves us in Jesus Christ our Lord. There is no way you can merit nor earn the favor of God. It comes to you only as the gift of God. Faith in Jesus Christ saves you by the grace of God. You cannot be good enough to merit God's favor. Grace is not for good people. Grace is for sinners, and that includes all of us (Romans 3:23).
Grace saves us from condemnation and everlasting punishment. It is by grace through faith we are saved (Ephesians 2:8-9). God works in and through us to do his will by grace. The Spirit of grace works in your heart, which is your mind, will, and emotions. God's grace gives you the ability and desire to do God's will (Philippians 2:13).
Grace is effectual to save us through Christ. It is not in vain. "But by the grace of God I am what I am, and his grace toward me was not in vain, but I labored more abundantly than they all, yet not I, but the grace of God which was with me" (First Corinthians 15:10). As a believer in Christ, you can say by the grace of God, I am what I am.
Grace saves us through a personal relationship with Christ. Grace reveals God in you through the Spirit of Christ (Romans 8:9). It's not what you do for God (Romans 11:6). Grace is what God has done for you in Christ. All that you are, or ever hope to be, is by God's grace in Christ.
