"You are sons of the prophets, and of the covenant which God made with our fathers, saying to Abraham, ‘And in your seed all the families of the earth shall be blessed.’" (Acts 3:25)
There’re Christians who say they have a covenant with God. They teach that since God made a covenant with Abraham, and we’re Abraham’s seed, we’re therefore automatically in covenant with God. But no; the Christian isn’t in covenant with God. You need to know who the Christian is; he’s one with Christ; he’s an associate of the God-kind. Abraham had a covenant with God, but we’re not in that covenant. Who are we? We’re children of the covenant. We’re heirs of God and joint-heirs with Christ.
"For you are all sons of God through faith in Christ Jesus. For as many of you as were baptized into Christ have put on Christ. There is neither Jew nor Greek, there is neither slave nor free, there is neither male nor female; for you are all one in Christ Jesus. And if you are Christ’s, then you are Abraham’s seed, and heirs according to the promise."
In a marriage relationship, for example, the couple sign a nuptial agreement and come into a covenant. That covenant, however, doesn’t involve their children. The children from that marriage would be the products or fruits of the covenant. Read our opening verse again, it’s clear: we’re children of the covenant that God made with Abraham and the patriarchs.
Many have written books on our covenant with God, but the danger of this misleading belief is that it places the Christian in a position below his calling and birthright. Our relationship with God is one of father and his children. Blessed thought! How wonderful to know that we’re heirs of God and joint-heirs with Christ. We’re children of the covenant! We own the world and we walk in divine excellence. Hallelujah!
All things are mine. I have everything that I require for life and godliness, because I'm an heir of God, and a joint-heir with Christ. I'm rich in all things because God has caused His grace to abound towards me to be superabundantly supplied, exceedingly fruitful, and productive in every good work. Hallelujah!
