Romans 8:26
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 through wordless groans. Romans 8:26 (NIV)
When you are so overcome that you do not have words know that you are not alone. God's love is so great that when your emotions are too intense to pray, the Holy Spirit intercedes for you. When words fail, His presence takes over:
Loving God, when my pain is too deep for words, I am comforted to know You will hear me.
