John 14:26 New International Version (NIV)
26 But the Advocate, the Holy Spirit, whom the Father will send in my name, will teach you all things and will remind you of everything I have said to you.
When you reach your limit in thinking and praying, let the Holy Spirit in. He moves on a higher plane in prayer. Every believer may live and move and pray in the Holy Spirit.
Dear Father, I have reached my limit. I do not understand many, many things. There is mystery in everything. I know that I can pray without ceasing through the Holy Spirit. Thank you for sending a Helper and a Teacher. Thank you. In Jesus’ Name I Pray, Amen.
