"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." (Romans 8:26)

Now if we don't know how to pray, then why pray at all? Understand this: Prayer is not getting my will done in Heaven, it's getting God's will done on Earth. It's not me giving direction to the Father, but rather me saying, "Father, direct me." God has chosen to work through the vehicle of prayer, and if we do not pray we will limit what He would do, what he could do, what He desires to do. 

Therefore, if I don't pray, I will never know if God got His way with my kids, with this congregation, or with our nation. But If I do pray and say, "Lord, here's the situation. I'm not directing You, but I'm just looking to You to have Your will done."-- Then I can be at peace. Whatever happens, I know I played my part; I opened the door, and since Father knows best, I can rest.

The Spirit groans through me, the Son intercedes for me, and the Father will do what's right concerning me. But if I don't pray, I'll always wonder if things would have been different if I had.
