The sinner who is saved and yet does nothing, is just as confused as the sinner who is saved and believes that they must do everything. Both extremes are reflections of pride. One says that they are so good that they don’t have to share the good news. The other says that they need to earn their way into heaven and as such, their works are greater than God’s grace. Both are a misunderstanding.
All the sinner has to do is receive what He’s done for us, of course God must also convict one of their unrighteousness and debt before Him as well..
A debt we can never hope to pay by our own ‘works’.
And thankfully, both are forgivable. I know of no one who has or practices perfect faith in grace. Each of us must rely on God’s gift to make it through.
