Accepting Christ in your heart gives you a rest inside. It’s something to believe, not behave.
The bottom line is this, Jesus Christ was the “last Adam” that took all of our sins and died for us.
On the third day He rose for our justification, and we now are perfect, holy and blessed because The Father treats us as a joint-heir with Christ, the Last Adam.
We are in the “much more” of the New Covenant.
If one man’s sin was powerful enough to make us all sinners…
Christ’s perfection is much more aggressive. We can always expect to be treated as a son and a bride (righteous, blessed, favored, and treated like Christ)
