Romans 8:14-17
“For as many as are led by the Spirit of God, these are the sons of God. For you did not receive the spirit of bondage again to fear, but you received the Spirit of adoption by whom we cry out, “Abba, Father”. The Spirit itself bears witness with our spirit that we are children of God and if children, then heirs – heirs of God and joint heirs with Christ, if indeed we suffer with Him, that we may also be glorified together.”
If we are regenerated children of God and led by His Spirit, we will exhibit His character and spiritual image. Before God summoned us, began to reveal His truth to us, forgave us, justified us, and imparted His Spirit to us, our spiritual father was Satan! We were no better than the Pharisees, whom Christ told that they were of their father, the Devil, because they were doing Satan’s works (John 8:39-47). Children display the characteristics of their parents, so Christ judged the Pharisees to be the children of Satan because they were exhibiting the Devil’s characteristics.
Before God intervened in our lives, we, too, were the children of Satan (Ephesians 2:1-3) because we were exhibiting his spiritual characteristics. However, God began to redeem us and called us into a relationship with Him, which, as Romans 8:15 says, was symbolically an adoption. God was not our original father, but He took on that role after He extracted us from the grasp of Satan, sin, and this world.
When we enter into Covenant with our Father and Jesus Christ, with access to the Holy Spirit, the quality of our witness must be much higher than what God expected even of ancient Israel. To whom much is given, much also is required (Luke 12:48)! If our neighbors, co-workers, or family members look at us, and all they see are people who go to church on different days, do not eat certain foods, give multiple tithes on their income, and do not believe in the Trinity, are they seeing anything different than Old Covenant Israel, who did not have the Holy Spirit? Certainly, God’s law will set us apart from the world because the world is against God, but merely keeping the letter of the law will not provide the complete witness that God is looking for.
