Peace. Another quality of the young church - peace more profound than the times in which they lived. Peace with God and with one another. The peace that comes from Hope based on who God is, and the Love He sheds abroad in our hearts, Faith that links our reality with God's reality and helps us line up with Him.
I pray the Lord's prayer more often as I get older, if only to reiterate, "Thy will be done" even if, especially if, I don't know what that is. I don't have to know what it is. I can pray with no doubt that God will accomplish His will. Looking back, when I found myself praying the Lord's prayer more and my own prayers less, maybe to acknowledge that's how Jesus taught His disciples to pray, there were some big, unexpected changes in my life - changes I never expected.
He talks about some of the things that fight with Peace: the need to resolve inner conflict, to share life with God, to accept ourselves as God made us and the resources He provides one day at a time, the need to align ourselves with God's purpose for us however seemingly insignificant.
And remember. There is an individual expression here but perhaps even more important, there was a group of believers learning to stand in awe of God's work - His visiting the earth, sending His son in the flesh, learning to live faith, to live hope, to live love and they became an unassuming force to be reckoned with.
