We can never make up for our sin by self-improvement or good works. Only by trusting in Jesus Christ as God’s offer of forgiveness can anyone be saved from sin’s penalty. When we turn from our self-ruled life and turn to Jesus in faith we are saved. Eternal life begins the moment one receives Jesus Christ into his life by faith.
