“but those who wait for the Lord shall renew their strength” Isaiah 40:31
There have been all sorts of suggestions about how to wait, but first and foremost it involves time. Time is what self & Satan conspire to keep from us, self because we want to fill our moments with what pleases us, and Satan because he intends that we never stop long enough to actually consider our Maker.
Our lives are so busy that we get used to the busyness. In fact we get so used to busyness that when we actually get some free time we hunt round for something to fill the gap, something to do.
What we should do is spend time with God: talk, listen, just be still & know His presence. I know people require quanity in order to cultivate that quality time we so desire; how much more important is it to cultivate quality time with God by spending quantity time with Him?
