Interesting. That begs the question of when a person becomes a Child of God. If someone is a Child of God and has therefore been adopted into the Family of God and is an heir with Christ, what then is the status of that person after he "falls from grace"? Wouldn't he still be a Child of God?
The children of Israel, our example, fell from “GRACE MANY, MANY TIMES.(1 Cor. 10:10-12) Each time God took them back when they repented...!(Ezk. 18:30) They were sitll His children but He punished them until they repented. If they didn’t repent, they died.(Heb. 3:17) He had to, God is righteous and has to punish sin or he becomes a liar.(Rom. 3:4-6) Sin seperated the children of Israel from God just as it seperates us, so either we, as children of God, repent of our sins our we die in our sins.(Jn. 8:24)
God, knowing that you and I will sin, added something to the “new covenant” that the “old covenant” didn’t have, GRACE. (Rom. 3:23 & Jn. 1:17) But, even with God’s grace, you and I can’t continue in sin, you and I have to be dead to sin. (Rom. 6:1-3) How do we accomplish that? By being in Christ....!(Rom. 3:23-25) If you and I are in Christ and are faithful, not perfect, God will forgive us our sins. You and I must walk in the light as Christ is in the light, then He will forgive us our sins. (1 Jn. 1:6-8, 2 Tim. 2:12-14) God rewards the faithful, not the unfaithful.(Matt. 24:44-46, Matt. 25:22-24,Lk. 12:34-36, Lk, 19:16-18,)
You and I just like the children have a decision to make, either we serve God or we serve satan for there are only two masters, God leaves that choice up to us.(Matt. 6:24, Lk. 16:13) Hopefully all will make the same choice that Joshua chose to make..! (Joshua 24:14-16)
