This is a song by Brenton Brown/Ken Riley written using Isaiah 40’s words that those who wait upon the Lord shall renew their strength and rise up on the wings of eagles. 
The song also embraces the prophet’s (and God’s) desire for justice for those in need–the weak and poor. For me, these needy and weak persons can be both us who sing these songs in worship and those who are poor in other ways. In either case our salvation is tied up together–in helping save others lives (not simply ‘souls’ but a more holistic salvation) through mission and service and evangelism–we also receive God’s salvation.
This subject of “waiting” is a popular one in the prophetic literature and in the Psalms. But, this type of waiting is (in my opinion) not what some would call christian “quietism” in the sense of passive waiting upon God to act or speak. This was a popular doctrine in catholic and protestant circles in the 17th century.
John Wesley, the Anglican priest and father of Methodism, said that christians must “attend to the ordinances of God.” That is that people striving to follow the ways of Jesus should actively wait upon God by going where God is conveyed. (And yes God is everywhere, but the argument can be made that God is better revealed and made known to us in certain places, spaces, and actions. In this is we who need a change of venue or pace in order to recognize the God that is ever-present.)
If you take a moment to think about where and how you have experienced God–in a moment, a place, or an action–you may discover a touchstone or ordinance (religious rite) that helps keep you in love of God and neighbor. How do you keep that ordinance or touchstone in your daily life now?
As one of my favorite seminary professors Rex Matthews has said of our participation in God’s work–if you want to catch the bus, you go to a bus stop…if you want to hear from/experience God, go to where God is.
Many experience this place/space at church in worship, communion, singing, praying, in conversation with friends and family, or in other ways. Whatever/where-ever it is, find it and go to it often. This is what John Wesley was talking about–where and how do you find/connect to God and what God is doing in, through, with and, even, in spite of you?
It is in our “active waiting“ in that place/space/event that we find strength to live and move and act in the world in ways that express the Love of Jesus Christ God.
