I've actually heard these teachings. They're out there in the church world that after you repent, you're no longer a sinner. You're a saint now, and you no longer have to repent anymore. You just keep on living, brother, and you just believe, and you name and claim, and you go get your stuff. And I'm thinking, boy, oh boy, what are you missing with the sweet joys of supplication and the tender mercies of God in that place of contrition because somebody taught you that you don't have to keep short accounts with God.
Repentance is absolutely necessary for salvation, but also I think a critical component to walking with Jesus day after day.
