Then in verse 26 we see what the Spirit does during of time of endurance, He prays for us. In verse 27 we see what the Father does in relationship to the Holy Spirit. And now at verse 28 we see what the Father does in relationship to us. As the believer suffers he is to endure by faith 2. As part of our faith we pray to the Father.
Prayer is a tremendous expression of faith.
The Holy Spirit prays for us and His prayers are answered. But the Holy Spirit may pray that it remain. So then, even when suffering remains, we have a promise that God is working all things together for His good, therefore our good. They make the subject all things. So while in some situations that could be okay, here we have the subject expressed within the verb.
