Then explain the "because" in verse 27 as deferring from the testimony of verse 26.
Ro 8:18-27
18 For I reckon that the sufferings of this present time are not worthy to be compared with the glory which shall be revealed in us.
Whatever we suffer now is nothing compared with what God has waiting for us.
19 For the earnest expectation of the creature waiteth for the manifestation of the sons of God.
For the earnest expectation our hope based on God’s promise
of the creature of we who are saved and are a new creation by our rebirth and adoptiom
manifestation of the sons of God
we are now adopted and are God’s children but we don’t look any different yet. The manifestation will be apparent when we receive our glorified bodies.
20 For the creature was made subject to vanity, not willingly, but by reason of him who hath subjected the same in hope,
subject to vanity ineffectual and frail
by reason of him who hath subjected the same because God has made us that way to teach us to depend on him
21 Because the creature itself also shall be delivered from the bondage of corruption into the glorious liberty of the children of God.
22 For we know that the whole creation groaneth and travaileth in pain together until now.
Mankind, unassisted by God, can do nothing to improve our condition
23 And not only they, but ourselves also, which have the firstfruits of the Spirit, even we ourselves groan within ourselves, waiting for the adoption, to wit, the redemption of our body.
We also who have the Holy Spirit still struggle with our sin nature while we await our glorified bodies.
24 For we are saved by hope: but hope that is seen is not hope: for what a man seeth, why doth he yet hope for?
Hope is faith is reliance on the truth of God’s word
we must rely on God’s promises even before they are received in full.
25 But if we hope for that we see not, then do we with patience wait for it.
26 Likewise the Spirit also helpeth our infirmities: for we know not what we should pray for as we ought:
but the Spirit itself maketh intercession for us with groanings which cannot be uttered.
27 And he that searcheth the hearts knoweth what is the mind of the Spirit, because he maketh intercession for the saints according to the will of God.
And he that searcheth the hearts is God whether the Father or the Son or both.
knoweth what is the mind of the Spirit understands the Spirit’s groanings
because he [the Spirit] maketh intercession for the saints according to the will of God.
