15 For you have not received a spirit of slavery that leads you into fear again. Instead, you have received the Spirit of adoption by whom we cry out, "Abba! Father!"
16 The Spirit himself testifies with our spirit that we are God's children.
17 Now if we are children, we are heirs—heirs of God and co-heirs with Christ, if, in fact, we share in his sufferings in order that we may also share in his glory.
