The ONLY connection. Through Jesus the power, the life, the hope, the eternal peace of Heaven flows into us into us through the Holy Spirit. In that power and life and hope and peace we can learn to grow in prayer. Without Christ you have none of that. God remains totally other.
Prayer remains distant.
You remain an alien to heaven. And no matter what all else you may learn about technique, or content, or process of praying, it will amount to absolutely nothing.
