“I WILL…” Hebrews 8:10-11 There is a clear contrast between the conditional “Thou shalt” of the first covenant and the free grace of the new covenant, “I will.” The first covenant was made with the nation of Israel. That legal agreement with Israel does not apply to Christians who are believers in the church, the body of Christ, which includes both Jews and Gentiles. To preach another Gospel that demands keeping the law is cursed [Gal. 1:8]. Israel did not continue to meet the demands of the covenant with God; now “God commands all men everywhere to repent.”
The new covenant is between the Father and the Son. The Son, our Lord Jesus Christ, acts as our representative in this covenant. He has done this for us through “the blood of the eternal covenant.” The “God of peace” is the one who provided what we needed when He sent His Son to be the Savior of the world. This covenant is entirely a work of God, and we are the beneficiaries! We can find rest for our souls because the Lord Jesus Christ completed the work the Father gave Him to do.
God will resume His dealings with Israel in the future, and “after those days,” good things will come to Israel. This is an unconditional fact in which their transgressions and iniquities will be removed because God will be merciful to them. All of this will happen after the Tribulation has passed. The “I wills” of God’s promises will be fulfilled. The external law will become a matter of the heart, and believing Jews will delight to do God’s will from their hearts. God will establish the covenant Himself through the Mediator and the Holy God. Then they will be able to have personal and direct fellowship with God.
By virtue of the new birth, a new heart, a new nature, and a new power given to them by God, believing Jews will keep the terms of the new covenant. This will not only affect our Christian life and conduct with God but also with our neighbors. They will experience a personal knowledge of God and the Lord Jesus Christ, much like Christians do today. People recognize when a personal relationship has been established. It is very different to know a person exists and to know them in a personal way.
The Lord Jesus said, “I know My sheep and My sheep know Me” in the same way the Father knows the Son and the Son knows the Father. We don’t create feelings or do anything to earn this relationship and the personal connection that follows. This comes as a gift from God. The new covenant offers eternal life and its blessings through God's mercy and grace. As God’s “little children,” we come to “know the Father.”
