I need to state here that my posts are not intended to be a full exposition of Old and New Testament surveys. I just want to get the general point across.
The New Testament is the revelation of the New Covenant, which was foretold in Jeremiah 31:31-34:
“Behold, the days are coming, declares the Lord, when I will make pa new covenant with the house of Israel and the house of Judah, not like the covenant that I made with their fathers on the day when I took them by the hand to bring them out of the land of Egypt, my covenant that they broke, though I was their husband, declares the Lord. For this is the covenant that I will make with the house of Israel after those days, declares the Lord: I will put my law within them, and I will write it on their hearts. And I will be their God, and they shall be my people. And no longer shall each one teach his neighbor and each his brother, saying, ‘Know the Lord,’ for they shall all know me, from the least of them to the greatest, declares the Lord. For I will forgive their iniquity, and I will remember their sin no more.”
If we are not teaching the born again walk from the position of the new covenant, as heirs of the kingdom, with the new nature implanted in us by the Holy Spirit, then all we are doing is preaching the law. The law, in essence, was a picture of what the new man would be like. Just preaching what we should do doesn’t get us there. It is merely recapping the law that we couldn’t keep in the first place.
Transformation comes from nurturing the seed of faith that was planted in us at the time we turned to the Lord to believe on him for our salvation.
Now the Lord is the Spirit, and where the Spirit of the Lord is, there is freedom. And we all, with unveiled face, beholding the glory of the Lord, are being transformed into the same image from one degree of glory to another. For this comes from the Lord who is the Spirit.
(2 Corinthians 3:17-18)
