Long before you woke up this morning and long after you go to sleep tonight, the Spirit of God was interceding for you with wordless groans. He has been praying you since the day you were conceived and He’ll pray for you till the day you die.
Mark Batterson wrote, "He is praying hard for you with ultrasonic groans that cannot be formulated into words and those unutterable intercessions should fill you with an unspeakable confidence." God isn’t just for you in some passive sense. God is for you in the most active sense imaginable: intercession.
“We do not know what we ought to pray for, but the Spirit himself intercedes for us through wordless groans.” Romans 8:26
Some times our prayers sound hollow to us and maybe they are, but not once the Holy Spirit get's finished translating them for the Father on your behalf. Your prayers are his prayers and they are Spirit breathed, groaned, to the Father.
Don't give up. Keep praying. Your prayers are powerful.
