For You are our Father, though Abraham does not know us And Israel does not recognize us. You, O LORD, are our Father, Our Redeemer from of old is Your name. Isaiah 63:16
An Amazing revelation by the prophet Isaiah, the God is not only the Father of Israel, but Gentiles also! There was going to come a day, when God would open up his covenant with the rest of the world through his Son Jesus Christ.
By the blood of Christ, no longer are we aliens or strangers to God, we become his Children. We become the children of God by the blood of Jesus Christ. We have entered into his eternal covenant that we will inherit the Promised Land of the New Heavens and Earth with Jesus Christ ruling from the throne
For you have not received a spirit of slavery leading to fear again, but you have received a spirit of adoption as sons by which we cry out, “Abba! Father!” Romans 8:15
When you are adopted , you are a legitimate child to that family. Joseph went to Bethlehem and he adopted/registered Jesus as his own son. Even though we know Jesus is the Son of God, by the adoption Jesus fulfilled the Line of David.
We as Christians have been adopted into Gods covenant. We are no longer slaves and strangers, we are Children of God, and we call our God “Abba Father”! Because of Jesus Christ we have all been made One with God. Because of Christ our Redeemer Amen!
