Perspectives on grace from Dietrich Bonhoeffer (The Cost of Discipleship):
Cheap grace means grace sold on the market like cheapjacks’ wares. The sacraments, the forgiveness of sin, and the consolations of religion are thrown away at cut prices. Grace is represented as the Church’s inexhaustible treasury, from which she showers blessings with generous hands, without asking questions or fixing limits. Grace without price; grace without cost! The essence of grace, we suppose, is that the account has been paid in advance; and, because it has been paid, everything can be had for nothing. Since the cost was infinite, the possibilities of using and spending it are infinite. What would grace be if it were not cheap?
Cheap grace is the preaching of forgiveness without requiring repentance, baptism without church discipline, Communion without confession, absolution without personal confession. Cheap grace is grace without discipleship, grace without the cross, grace without Jesus Christ, living and incarnate.
Cheap Grace from Got Questions dot Org,
Cheap grace seeks to hide the cost of discipleship from people. It seeks to claim that as long as we make a profession of faith, we are saved. God’s grace covers all our sins. Again, that is a wonderful truth! The apostle Paul says as much when he writes, “Now the law came in to increase the trespass, but where sin increased, grace abounded all the more, so that, as sin reigned in death, grace also might reign through righteousness leading to eternal life through Jesus Christ our Lord” (Romans 5:20-21). Yet, right after writing that, Paul follows it with this: “What shall we say then? Are we to continue in sin that grace may abound? By no means! How can we who died to sin still live in it?” (Romans 6:1-2). Salvation by grace alone through faith alone is so much more than simply mouthing the words “Jesus is Lord.” We are not saved by a profession of faith. We are not saved by praying the Sinner’s Prayer. We are not saved by signing a card or walking an aisle. We are saved by a living and active faith (James 2:14-26), a faith that manifests itself in repentance, obedience and love of God and our neighbor. Salvation is not a transaction; it’s a transformation. Paul says it best when he says we are “new creations” in Christ (2 Corinthians 5:17). There is nothing “cheap” about grace!
