The Scriptures call us to pray continuously, moment to moment. When we do not pray, the need of the moment remains — and often drives us to unhelpful responses, such as anxiety. Paul Miller, in his book A PRAYING LIFE, illustrates this, beginning with the “unused” prayer of that moment…
What does an unused prayer link look like? Anxiety. Instead of connecting with God, our spirits fly around like severed power lines, destroying everything they touch. Anxiety wants to be God but lacks God’s wisdom, power or knowledge. … Because anxiety is self on its own, it tries to get control. It is unable to relax in the face of chaos. Once one problem is solved, the next in line steps up. The new one looms so large we forget the last deliverance. (p. 70)
1st Peter 5:7 tells Christians to be casting all your anxieties on him, because he cares for you.
