So you have not received a spirit that makes you fearful slaves. Instead, you received God’s Spirit when He adopted you as His Own children. Now we call him, “Abba, Father.” For His Spirit joins with our spirit to affirm that we’re God’s children.
Under the old covenant of Law, people received a spirit that made them fearful of God and saw themselves as slaves. It was only in the New Covenant of Grace, Jesus came to Reveal God as Father and then we are able to be free from the Old Covenant Law of Moses type fear of God and thus cry out, “Abba, Father!!!”
