What the Bible says about Remnant
(From Forerunner Commentary)
Paul specifically says that the law will be written in the fleshly tables of our heart by the Spirit of the living God! However, the circumcision of the heart is a co-operative effort. God does His part, and we do ours by submitting to Him. Both parts are involved within this process, by which God is enabling us to have the power to sustain a relationship with Him. And that power is given only to the children of promise, the children of God, the church, the remnant, those who are in Christ, those who have received God's Spirit.
