Mt 6:27 And which of you by being anxious can add a single hour to his span of life? Worry is a waste of time. Time wasted on fruitless worry means time not spent in obedience. The greater the worry, the greater the waste of time. Excessive worry makes you ineffectual. Satan loves worriers because they aren’t serving God but are slaves of their own cares.
Mt 6:24 No one can serve two masters, for either he will hate the one and love the other, or he will be devoted to the one and despise the other. You cannot serve God and money. If you are a worrier, you are given time which belongs to God and wasting it. Your mind is consumed with the world and your life and whatever else it is you worry so much about. Worry seems to have a lot to do with the development of doubt and subsequent instability which in turn leads to susceptibility to temptation, then sin, then – gulp – death. It is a wide road.
