16 The Spirit itself beareth witness with our spirit, that we are the children of God:
17 And if children, then heirs; heirs of God, and joint-heirs with Christ; if so be that we suffer with him, that we may be also glorified together.
English Standard Version
16 The Spirit himself bears witness with our spirit that we are children of God,
17 and if children, then heirs--heirs of God and fellow heirs with Christ, provided we suffer with him in order that we may also be glorified with him.
16 God's Spirit touches our spirits and confirms who we really are. We know who he is, and we know who we are: Father and children.
17 And we know we are going to get what's coming to us - an unbelievable inheritance! We go through exactly what Christ goes through. If we go through the hard times with him, then we're certainly going to go through the good times with him!
New King James Version
16 The Spirit Himself bears witness with our spirit that we are children of God,
17 and if children, then heirs--heirs of God and joint heirs with Christ, if indeed we suffer with Him, that we may also be glorified together.
New Living Translation
16 For his Spirit joins with our spirit to affirm that we are God's children.
17 And since we are his children, we are his heirs. In fact, together with Christ we are heirs of God's glory. But if we are to share his glory, we must also share his suffering.
If the Spirit be in us, Christ is in us. He dwells in the heart by faith. Grace in the soul is its new nature; the soul is alive to God, and has begun its holy happiness which shall endure for ever. The righteousness of Christ imputed, secures the soul, the better part, from death. From hence we see how much it is our duty to walk, not after the flesh, but after the Spirit. If any habitually live according to corrupt lustings, they will certainly perish in their sins, whatever they profess. And what can a worldly life present, worthy for a moment to be put against this noble prize of our high calling? Let us then, by the Spirit, endeavour more and more to mortify the flesh. Regeneration by the Holy Spirit brings a new and Divine life to the soul, though in a feeble state. And the sons of God have the Spirit to work in them the disposition of children; they have not the spirit of bondage, which the Old Testament church was under, through the darkness of that dispensation. The Spirit of adoption was not then plentifully poured out. Also it refers to that spirit of bondage, under which many saints were at their conversion. Many speak peace to themselves, to whom God does not speak peace. But those who are sanctified, have God's Spirit witnessing with their spirits, in and by his speaking peace to the soul. Though we may now seem to be losers for Christ, we shall not, we cannot, be losers by him in the end.
