Amplified Bible (AMP)
25 But if we hope for what we do not see, we wait eagerly for it with patience and composure.
Our Victory in Christ
26 In the same way the Spirit [comes to us and] helps us in our weakness.
We do not know what prayer to offer or how to offer it as we should, but the Spirit Himself [knows our need and at the right time] intercedes on our behalf with sighs and groanings too deep for words. 27 And He who searches the hearts knows what the mind of the Spirit is, because the Spirit intercedes [before God] on behalf of God’s people in accordance with God’s will.
28 And we know [with great confidence] that God [who is deeply concerned about us] causes all things to work together [as a plan] for good for those who love God, to those who are called according to His plan and purpose.
In the same way, the Spirit helps us in our weakness. We do not know what we ought to pray for, but the Spirit himself intercedes for us through wordless groans.
