Martyn Lloyd-Jones wrote, "It is grace at the beginning, and grace at the end. So that when you and I come to lie upon our deathbeds, the one thing that should comfort and help and strengthen us there is the thing that helped us in the beginning. Not what we have been, not what we have done, but the Grace of God in Jesus Christ our Lord."
The fullness of God's grace is unmerited favor. That's the grace of God in Christ. It is the gift of God that can only be received by faith alone (Ephesians 2:8-9). Grace is not what we have done, but what God has done for us in Jesus Christ our Lord.
The fullness of grace is in Christ alone. He is the fullness of grace (John 1:16). God's grace was in Christ dying for our sins (Hebrews 2:9). God's grace was at the empty tomb. He is risen for our justification (Romans 4:25). He lives as our sanctification (1 Peter 1:2). He is coming again for our glorification (Romans 8:30). That's the fullness of grace in Jesus Christ our Lord.
Lloyd-Jones was saying that the Christian life is by God's grace in Christ alone. It is grace in three tenses, past, present and future. He said, "The Christian life starts with grace, it must continue with grace, it ends with grace." It's the fullness of grace in Christ, from the beginning unto the end..
