Does the Bible teach that being under grace means you can do whatever you please?
No. Scripture never teaches that being under grace gives license to sin or do whatever one pleases. Paul says such a claim was slanderously reported against him, and those who affirm it face sure condemnation. Believers are saved by grace, live by grace, and walk by grace, not in license.
Les explains that the idea that being under grace means a person is saved and can now do as he pleases is a false charge. Scripture never teaches that. Paul says this was slanderously reported, as some affirmed that he taught, "Let us do evil, that good may come," and he says their condemnation is sure. Such a report was meant to drag Paul's ministry down by claiming that once saved by grace, a person is at liberty to do whatever he wants. Les emphasizes that yes, we are saved by grace, we live by grace, and we walk by grace, but that is not license. In Romans 5:20, no matter how far down an individual can go into sin and wickedness, the grace of God is always capable of going even lower and bringing him back up to a place of righteousness.
