<p>8:10 <i>For this is the covenant that I will make with the house of Israel after those days, says the Lord. I will put my laws into their mind and in their heart also will I write them, and I will be to them a God and they shall be to Me a people</i>- A new covenant was needed because Israel had not kept the old covenant, they had broken their covenant relationship (see on :9); God had &quot;found fault&quot; with them (:8). The covenant proposed here was to be written by God in human hearts rather than on tables of stone, to which obedience was demanded. God would &quot;be to them a God&quot; in that this was part of the promises to Abraham (Gen. 17:7,8) which are the &quot;better promises&quot; forming the new covenant (see on :6). This new covenant which was to be made with Israel has now been made with us in this life (cp. :13). The promises which comprised the new covenant were those made to Abraham; but they referred only to Abraham and his one singular seed (Gal. 3:16). Once the seed had come, we are able to be baptized into Christ so that all that is true for Him becomes true for us (Gal. 3:27-29). As the full and totally inclusive representative of all humans, the Lord Jesus thereby opened the way for the promises to Abraham to actually become the new covenant in practice for all who become in Him. The promise to Abraham and his Messianic seed just two people that &quot;I will be their God&quot; thereby becomes true for an entire people; &quot;they who are in Christ shall be to Me a people&quot;. Entry into the new covenant therefore involves God writing upon our hearts, which is done through the work of His Spirit operating directly upon the hearts of all those baptized into the seed (2 Cor. 3:3).</p>
