Since we believe that Christ died for all, we also believe that we have all died to our old life. He died for everyone so that those who receive his new life will no longer live for themselves. Instead, they will live for Christ, who died and was raised for them. … This means that anyone who belongs to Christ has become a new person. The old life is gone; a new life has begun! [2 Corinthians 5: 14b-15,17 (NLT)]
Sanctification is the work of God’s free grace, whereby we are renewed in the whole man after the image of God, and are enabled more and more to die unto sin, and live unto righteousness. [Westminster Shorter Catechism]
In writing about the Sinner’s Prayer yesterday, I wondered if, by saying it, a new believer gets the false impression that his responsibility ends with a prayer when, in fact, it has just begun! Justification takes only a moment but sanctification takes a lifetime. Addressing the guilt of our sins, justification is when, by the grace of God, we are made righteous through God’s grace and our faith. It’s as if we’re guilty criminals, standing in God’s courtroom, and God pardons us. Telling us our debt to society has been paid, He sets us free. While it’s easy to walk out of the courthouse, it’s not so easy to alter the behavior that led to our life of crime. Like any felon, we need to change our ways, which is where sanctification comes in. Rather than the reformation of a criminal, it is the transformation of a sinner.
Powered by our faith and the Holy Spirit, sanctification transforms our sinful character so we grow more and more like Christ. Focusing on the destructive power of sin in our lives, it gradually shapes our hearts, minds, and desires to those of God. Sanctification is the work part of our salvation and requires diligence in study, prayer, fellowship, witness and service. It’s coming to know Jesus, loving and obeying God, and letting both His word and the Holy Spirit convict us when we sin. It’s allowing God to work in and through us, not as a way to earn His blessings and favor, but because we delight in His will.
While holiness is the goal of sanctification, I don’t think any mortal can live a life completely free from sin in this world. Nevertheless, even though we can’t attain sinless perfection, like the Apostle Paul, we will continue to struggle against sin and temptation as long as we’re on this side of the grass. We persevere and, through the power of the Holy Spirit, continue to grow more and more like Christ every day.
The Christian life requires hard work. Our sanctification is a process wherein we are coworkers with God. We have the promise of God’s assistance in our labor, but His divine help does not annul our responsibility to work. [R.C. Sproul]
