One of the most constant dangers that Christians face is the temptation to think that our sin is greater than God’s grace. It isn’t. Paul points this out rather extensively in Romans 5:15-17, where the entire theme is “how much more” is God’s grace than all sin in the world. Phillip Melanchthon’s commentary on the passage is worth quoting here for its pastoral sensitivity:
“The godly should diligently consider this superiority of grace in order that they may oppose it to the magnitutde of their sin and to their present weakness. No sin, no matter how great, ought to be considered greater than grace (p. 139 of the Kramer translation).”
