Galatians 4: 6-7. And becuse ye are sons, God hath sent forth the Spirit of His Son into your hearts, crying Abba, Father. Wherefore thou art no more a servant, but a son; and if a son, then an heir of God through Christ.”
Salvation has always come by faith. The diligent keeping of the Law did not make a person sure of heaven; it was by faith that the Old Testament saints believed God. They kept the Law as an indicator of their faith in God, and out of reverent obedience to His Word. When they taught their children the Law, they taught about the great and holy Yaweh Who had given them the law to bring them to an understanding of their sin.
Since Christ’s finished work at Calvary, every true believer is indwelt by the Holy Spirit of God, sealed and anointed. Anyone who does not have that indwelling of the Holy Spirit is not a true believer. Because He dwells in our hearts, as we grow in understanding and knowledge of Him and Who He is, we look with adoration and reverence into His face and cry, “Abba, Father.” Both Jew and Gentile now have this free access to God, by grace, through faith.
Because we now have the Holy Spirit, we are indeed no longer in the place of servants, but of sons. As sons, we are heirs of all His possessions through Christ Jesus our Lord.
Do you sometimes find yourself thinking, “Yes, I know this. I believe it is true. But I have a really hard time getting my head around the idea that I have the same standing with God as His Son does, and that my heavenly inheritance is equal with His. How can this be?”
I know only that it is through the unlimited grace and love of God that it is possible. To know it now is amazing. To experience it there? I can’t even begin to imagine.
