Romans 8:15-17
8:15 For you did not receive the spirit of slavery leading again to fear, but you received the Spirit of adoption, by whom we cry, “Abba, Father.”
8:16 The Spirit himself bears witness to our spirit that we are God’s children.
8:17 And if children, then heirs (namely, heirs of God and also fellow heirs with Christ) – if indeed we suffer with him so we may also be glorified with him.
Romans 8:29-32
8:29 because those whom he foreknew he also predestined to be conformed to the image of his Son, that his Son would be the firstborn among many brothers and sisters.
8:30 And those he predestined, he also called; and those he called, he also justified; and those he justified, he also glorified.
8:31 What then shall we say about these things? If God is for us, who can be against us?
8:32 Indeed, he who did not spare his own Son, but gave him up for us all – how will he not also, along with him, freely give us all things?
