We all have times when we feel weak and don't know what to do. The Holy Spirit helps US align with God's will by interceding for us during those times.
"In the same way, The spirit helps us in our weaknessess. We do not know what we ought to pray for, but the spirit himself intercedes for us throught wordless groans. And he who searches our hearts know the mind of the spirit because the Spirit intercedes for God's people on accordance with the will of God"
(Romans 8:26-27).
