The Holy Spirit also testifies to us about this. First he says: 16
“This is the covenant I will make with them after that time, says the Lord. I will put my laws in their hearts, and I will write them on their minds.”
17 Then he adds:
“Their sins and lawless acts I will remember no more.”
18 And where these have been forgiven, sacrifice for sin is no longer necessary.
23 Let us hold unswervingly to the hope we profess, for he who promised is faithful. 24 And let us consider how we may spur one another on toward love and good deeds, 25 not giving up meeting together, as some are in the habit of doing, but encouraging one another—and all the more as you see the Day approaching.
Hebrews 10:15-18,23-25
