God’s Spirit helps us to pray. So we look to the Spirit to direct and guide and show us how to pray. There are many times when we don’t know what to pray, but the Spirit takes those groans and brings them to the Father.
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. And he who searches our hearts knows the mind of the Spirit, because the Spirit intercedes for God’s people in accordance with the will of God.
