Likewise the Spirit helps us in our weakness. For we do not know what to pray for as we ought, but the Spirit himself intercedes for us with groanings too deep for words. Romans 8:26 (ESV)
Why Do We Pray?
Adoration - We give praise and love to God. Confession - We acknowledge our sin and our need for a savior. Thanksgiving - We thank God for for what he has done for us in our life. Supplication - We turn to God with our needs.
