Our Father, which art in heaven, hallowed be Thy name...is the door to the mind of God. We must love him more than we love ourselves. The central theme of our very being must be caught up in His priceless Person. To enter into the realm of prayer, Jesus must be Lord, for prayer is not a position but a person, Jesus Christ.
"Roll your works upon the Lord-commit and trust them wholly to Him: (He will cause your thoughts to become agreeable to His will and so shall your plans be established and succeed." Proverbs 16:3
We must be totally and completely yielded to the Lord, in the process of prayer.
