Grace is undeserved and unmerited favor from God. It enables us to be saved and have eternal life in Jesus Christ. We all have failures and shortcomings, and no one can truly say that they have lived such a life that would cause them to deserve God's unmerited favor. Being saved by grace means receiving God’s undeserved favor and mercy rather than relying on our own efforts or worthiness. This grace is fully given through Jesus’ sacrifice for all who trust in Him for the forgiveness of sins. Grace does not end once we are saved; we need grace as we continue to grow and walk with Him. Grace also does not permit us to sin and live however we want, knowing God will forgive us. Rather, grace gives us the power to live transformed lives in gratitude and obedience. Salvation by grace assures us that we are accepted, forgiven, and sustained entirely by God’s love.
We are saved by grace, and we live by grace. Some people think that once they have been saved by the grace of God it means that they can sin as much as they want, because they are "covered" by God's grace. It is quite the contrary. God's grace is not an excuse for us to sin. Rather, it is God's grace that saves us and it is God's grace that trains and enables us to live righteous lives (Titus 2:11-14).
Others think that after being saved by grace we must do good works to maintain our salvation. But, again, it is quite the contrary. We are maintained by God's grace, not our own efforts. Good works do result from salvation, but they are the fruit of God's work in us (Galatians 5:22-24). We will still fail as believers, but God is faithful to forgive us (1 John 1:9). We can trust that we are justified by His grace and eternally secure in it (John 6:39–40).
If we were left on our own, we would continue sinning and running from God, but He draws us to Himself (John 6:44). When we put our faith in Christ and His redemptive crucifixion for our sins, God justifies us with His grace and credits our faith as righteousness (Romans 4:5). God justifies us when we don't deserve it. Thank God for His never-ending grace toward us.
