Prayer shouldn't add stress! And yet, I can get all worked up over how to pray.
I'm so thankful God knows we don't even know how to pray. I'm glad He knows I'm an idiot when it comes to how everything should be done; my weak words can't compare to His infinite wisdom. Even through all of that, He works through our prayers. That's a whole other article, though.
"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).
