Romans 8:15; Romans 8:23

15 For you did not receive a spirit of slavery to bring you back again into fear; on the contrary, you received the Spirit, who makes us sons and by whose power we cry out, "Abba!" (that is, "Dear Father!").

23 and not only it, but we ourselves, who have the firstfruits of the Spirit, groan inwardly as we continue waiting eagerly to be made sons - that is, to have our whole bodies redeemed and set free.
