Moses prayed that God would reveal Himself, show him His glory and let him see His kingdom. This is the revelation that God responded with and it reminds me of how I should come to my God in prayer.
The Lord came down in a cloud, stood with him there, and pronounced his holy name, the Lord.[a] The Lord then passed in front of him and called out, “I, the Lord, am a God who is full of compassion and pity, who is not easily angered and who shows great love and faithfulness. I keep my promise for thousands of generations[b] and forgive evil and sin; but I will not fail to punish children and grandchildren to the third and fourth generation for the sins of their parents.”
Moses quickly bowed down to the ground and worshiped. – Exodus 5:8 GNT
This is my God – the one I serve – who reigns as Lord and King over all – the one I will worship.
When I am therefore asked, but it is in the form of a commandment, to love one another, it matters.
And now I give you a new commandment: love one another. As I have loved you, so you must love one another. – John 13:34 GNT
It encapsulates all the others and expresses God’s entire will – His plan already in heaven to be realized here on earth. Through prayer I know what His will is and He gives me all the resources I need to accomplish it – may I be obedient.
Somehow I see Moses on his knees when he engages with God. I see Paul on his knees too when he prays prayers like this. He talks about God’s love as well.
For this reason I fall on my knees before the Father, from whom every family in heaven and on earth receives its true name. I ask God from the wealth of his glory to give you power through his Spirit to be strong in your inner selves, and I pray that Christ will make his home in your hearts through faith. I pray that you may have your roots and foundation in love, so that you, together with all God’s people, may have the power to understand how broad and long, how high and deep, is Christ’s love. Yes, may you come to know his love—although it can never be fully known—and so be completely filled with the very nature of God. – Ephesians 3:14-19 GNT
Typically, Jewish prayers are offered standing up. Paul is on his knees because he is in the presence of his King. We worship with a sense of reverence and respect. There is intimacy in prayer for even as the Sovereign God He is my Father. There is no rule that I need to be on my knees, it is the posture I find myself sometimes when I am in His presence. I love the presence of the Trinity in Paul’s prayer too.
“It may happen occasionally that I may get lost among so many ideas in one petition that I forgo the other six (the Lord’s prayer). If such an abundance of good thoughts comes to us, we ought to disregard the other petitions, make room for such thoughts, listen in silence, and under no circumstances obstruct them. The Holy Spirit preaches here, and one word of his sermon is far better than a thousand of our prayers.” – Luther
