"In recent years Christians have tended to focus on the death of Christ almost to the neglect of His sinless life. Jesus' life of perfect obedience has been seen mostly as a necessary precondition to His death. However, Jesus not only died for us; He also lived for us. All that Christ did in both his life and death, He did in our place as our substitute."— Jerry Bridges, Holiness Day By Dad, 44.
Remember that Jesus didn't only die for you, he lived for you! Because Jesus had to be without sin in order to be the perfect sacrifice, he lived for you and for me as he was living his life. He lived for you, so he could die for you!
