The New Covenant is at Work at All Times

The New Covenant is as follows:

"For this is the covenant that I will make with the house of Israel after those days, saith the Lord; I will put my laws into their mind, and write them in their hearts: and I will be to them a God, and they shall be to me a people:

"And they shall not teach every man his neighbour, and every man his brother, saying, Know the Lord: for all shall know me, from the least to the greatest.

  "For I will be merciful to their unrighteousness, and their sins and their iniquities will I remember no more." (Hebrews 8:10-12)

We can trust that God is moving on our behalf, working in our lives, because He promised to do so.

What enforces this New Covenant? That God does not remember our sins, because He has provided a propitiation, or "mercy seat" for our sins through Jesus Christ:

"And he is the propitiation for our sins: and not for ours only, but also for the sins of the whole world." (1 John 2: 2)

Some think that Jesus died for all the sins of the world, only, that His sacrifice only covers people and places.

In the previous chapter, John explains the total and eternal sacrifice that Jesus has provided for us:

"But if we walk in the light, as he is in the light, we have fellowship one with another, and the blood of Jesus Christ his Son cleanseth us from all sin." (1 John 1: 7)

The blood of Jesus Christ cleanses us, right now and forever more.

This blood speaks forth better promises, too:

"And to Jesus the mediator of the new covenant, and to the blood of sprinkling, that speaketh better things than that of Abel." (Hebrews 12: 24)

Jesus is (present tense) the mediator of the new covenant, our High Priest forever (Hebrews 5: 6), who lives an unending life (Hebrews 7: 16).

The keeps on cleansing us, the High Priest keeps on ministering for us, and thus the New Covenant is in full force forever, at work at all times in our lives!
