Romans 8:15

Romans 8:15. For ye have not received the spirit of bondage again to fear;

Ye did receive it once, and it was a great blessing to you. This came of the law, and the law brought you under bondage through a sense of sin, and that made you first cry for liberty, and then made you accept the liberating Saviour; but you have not received that spirit of bondage again to fear.

Romans 8:15. But ye have received the spirit of adoption, whereby we cry, Abba, Father.

We who believe in Jesus are all children of God, and we dare to use that name which only children might use, "Abba;" and we dare use it even in the presence of God, and to say to him, "Abba, Father." We cannot help doing it, because the spirit of adoption must have its own mode of speech; and its chosen way of speaking is to appeal to the great God by this name, "Abba, Father."
