God's grace is received as unmerited favor. There is no way we can merit nor earn the favor of God. It comes to us only as the gift of God. Faith in Jesus Christ receives God's saving grace. Don't fall for the idea that you can somehow be good enough to merit God's favor. Grace is not for good people. It's for sinners, and that includes all of us. For all have sinned and come short of the glory of God (Romans 3:23).
God's grace is received as deliverance from the curse of sin and death, through Christ our Lord. God's saving grace works in us to believe on the Lord Jesus Christ (Acts 16:31). God's grace comes to us by faith in Christ (Ephesians 2:8-10).
God's grace is received through the Gospel of our Lord Jesus Christ (1 Corinthians 15:1-4). To receive the Gospel is to believe Christ died for your sins on the cross (Romans 5:8). To receive the Gospel is to believe in the resurrection of Jesus Christ and confess him as your Lord (Romans 10:9).
God's grace is received in Christ alone. Christ Jesus came into the world to save sinners (1 Timothy 1:15). We have all sinned (Romans 3:23). God's grace is received in Christ crucified for all our sins (1 John 1:7). God's grace is received by faith in Jesus Christ our Lord.
