Or... how about we can't ask unless God makes us ask or until the Holy Spirit prays for what we know not how to pray for our self.
You bring up a very good point of teaching there, notice this is what Romans 8 says.
26 Likewise the Spirit also helps in our weaknesses. For we do not know what we should pray for as we ought, but the Spirit Himself makes intercession for us with groanings which cannot be uttered. 27 Now He who searches the hearts knows what the mind of the Spirit
is, because He makes intercession for the saints according to
the will of God.
The Holy Spirit makes intercession, meaning an intervention on our behalf with God according to the will of God.
So truly God is at work behind the scenes of our lives, the groanings which can not be uttered, invisibly imperceptible to us, but they are there.
The Holy Spirit is actively at work in His people and also for those who will become His people. The Holy Spirit is the HE who searches the hearts, and HE, the Spirit, knows what the mind of God is in every situation, since of course HE is God, and all things proceed according to the will of God for us. What a great way Paul teaches here of how much God cares for His own elect who are His, the saved and also those who will become the saved.
Which then Paul tells us how great is our salvation in these following scriptures.
28 And we know that all things work together for good to those who love God, to those who are the called according to
His purpose. 29 For whom He foreknew, He also predestined
to be conformed to the image of His Son, that He might be the firstborn among many brethren. 30 Moreover whom He predestined, these He also called; whom He called, these He also justified; and whom He justified, these He also glorified.
God’s Everlasting Love
31 What then shall we say to these things? If God
is for us, who
can be against us?32 He who did not spare His own Son, but delivered Him up for us all, how shall He not with Him also freely give us all things?
33 Who shall bring a charge against God’s elect? It is God who justifies. 34 Who is he who condemns? It is Christ who died, and furthermore is also risen, who is even at the right hand of God, who also makes intercession for us. 35 Who shall separate us from the love of Christ?
Shalltribulation, or distress, or persecution, or famine, or nakedness, or peril, or sword?36 As it is written:
“For Your sake we are killed all day long;
We are accounted as sheep for the slaughter.”
37 Yet in all these things we are more than conquerors through Him who loved us.38 For I am persuaded that neither death nor life, nor angels nor principalities nor powers, nor things present nor things to come, 39 nor height nor depth, nor any other created thing, shall be able to separate us from the love of God which is in Christ Jesus our Lord.
