What do you mean you don't mean to rest in your sins but to rest in Christ. What does resting in Christ look like that you're talking about?If we confess our sins, He is faithful and just to forgive our sins and to cleanse us from all unrighteousness. 1 John 1:9
So if you already have believed on the Lord, and you are a born again child of God....after that, you rest in Christ and in His finished work on the cross for you.
I'm not saying you rest in your sins. But in Christ.
Are you tormenting yourself? That is why I said learn to rest in Christ.
