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 with groans that words cannot express. And he who searches
our hearts knows the mind of the Spirit, because the Spirit
intercedes for the saints in accordance with God’s will.
-- Romans 8:26-27

Sometimes our prayers seem to bounce off the ceiling and fall to
the floor. Other times, we are overcome with emotion and the words
of our prayers can't capture what's in our hearts. Thank God for
the assurance that the power of our prayers is not dependent upon
our words, but upon his grace given us by the Holy Spirit's
intercession!
