Romans 8:15 (AMP) "For the Spirit which you have now received is not a spirit of slavery to put you once more in bondage to fear, but you have received the Spirit of Adoption (the Spirit producing sonship) in the bliss of which we cry Abba, Father!"
What does this mean? When we were born into this world, we were born in sin. the Psalmist said in Psalm 51:5, "I was brought forth in a state of iniquity; my mother was sinful who conceived me, and I too am sinful". Ephesians 2:3 says that we "were by nature the children of wrath...".
So, being born in sin, were not the children of God, but we were born by nature as children of the devil. Jesus, speaking to the Jewish leaders in John 8:44 said, You are of your father the devil, and the lusts of your father you will do...". 1 John 3:8 says that who willingly, knowingly and habitually commits sin is of the devil. Verse 10 goes on to say that whoever does not conform to God's will in purpose, thought and action is not of God and neither is anyone who does not love his brother.
Do you remember growing up and having pickup games on the neighborhood sandlot? Do you remember ever being on a team only because you were the only one left at the end of choosing teams? It was an experience that left you feeling anything but special. Such is not the case with God. You are very special to Him. 1 Peter 2:9-10 “But you are a chosen generation, a royal priesthood, a holy nation, a peculiar people, that you should show forth the praises of Him Who has called you out of darkness into His marvellous light; who once were not a people, but are now the people of God…”. The phrase “chosen generation” means select, favorite offspring. With that in mind you could read the beginning of our text “But you are a select and favorite offspring”. Unlike the situation in the sandlot, God has not left you to chance, but He has personally selected you as one of His favorites to be a member of His team.
