"Pray without ceasing," Paul writes to the church in Thessalonica (1 Thess. 5:17). And I take that to mean that we are to find times and ways of praying Monday through Saturday, and not reserve our prayer time for an hour on Sunday morning.
There are many ways of praying throughout the week. We can, and should, set aside a time each day to be quiet and listen for God and share with God what is on our heart. But even apart from that set time, there are ways to pray, some of which go beyond even our words. We simply call to mind something or someone we are concerned about, or we laugh at a memory, or our eyes get a bit misty when we think of a kindness we have received, or we are grateful for a delicious tomato or for a friend. When we are aware of them and when we offer them to God, these thoughts and feelings become prayer, with or without words.
There is a little copper bell that hangs just outside my back door. Often, when I am leaving the house, I reach up, give it a tap and a jingle, and think of someone at random. It is my prayer for them for that day; usually not even a specific prayer, just the wish that they are well and gratitude that they are in my life. You have probably been one of those for whom I have prayed this simple prayer of well-being.
