From John Piper's Desiring God website...
Here’s what is present when we kneel to pray in Jesus’ name:
1. God the Father on his throne sovereign over the universe, with a welcoming, countenance focused on us.
2. God the Son in his high priestly role, standing as advocate before the throne as a Lamb that was slain with perfect righteousness and with all God’s promises purchased fully in his hand interceding for us.
3. God the Spirit within us, having already inclined us to pray, poised to guide our prayers, put to death our sins, awaken our faith, illumine God’s word, and produce his fruit.
4. The word of God open before us, inspired by God, alive with penetrating power for conviction of sin and indomitable hope, revealing the Father, the Son, and the Spirit to our souls, shaping and guiding our prayers after God’s will.
5. Our sin forgiven, but humbling us to need and love our merciful saving God.
6. God’s grace like a great rainbow of hope arcing from the throne to our soul.
7. Our will captured by these realities, moving words (or only groans) up out of our mind (or only heart) to God with praise and thanks and confession and requests.
