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."
It's all of grace as God's unmerited favor for you. That's the grace of God in Christ alone (Acts 4:12). It is the gift of God that you can only receive by faith (Ephesians 2:8-9). Grace is not what you have done, but what God has done for you in Jesus Christ our Lord.
It's all of grace for your salvation in Christ. "And of His fullness we have all received, and grace for grace" (John 1:16). God's grace is Christ dying for your sins (Hebrews 2:9). God's grace is at the empty tomb. He is risen for your justification (Romans 4:25). He lives as your sanctification (1 Peter 1:2). He is coming again for your glorification (Romans 8:30). It's all by God's grace for you in Jesus Christ our Lord.
Lloyd-Jones was saying that the Christian life is all of grace in Christ. 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 all of grace for you in Christ, from the beginning unto the end..
