God tells us that we must kill the deeds of the body. So you should not be disheartened that you still have sin in the flesh to execute. No despairing allowed when sin pops up. You have executed sin before. You can do it again. As you do, you must show your sin no mercy. You are not your sin. Mercy is all over you. But your sin doesn’t get one drop of it.
With that foundation laid, let’s kill the sin of worry. Worry is a beast. Worry is a monster. But she’s a sneaky monster. Worry would have you think she is a weak, pitiable puppy who has lost her way down a dark alley in a bad part of town. She wants your sympathy. “I am a most reasonable sin,” she says. “We live in a fallen world with trouble around every corner.” She wants to woo you into an alternate universe where you rule and God doesn’t.
Worry is flamming pride in masquerade, which is why worrywarts regularly manipulate others. Worry is a momentary lapse of faith in the god of self that you never should have been trusting in the first place. The death blow to this sin involves you trusting the Living God who rules on the sunny mountain and in the dark alley.
So hear and believe these words from God, worry will then die and you will be moving on: “Thus saith God the Lord, He that created the heavens, and stretched them out; He that spread forth the earth, and that which cometh out of it; He that giveth breath unto the people upon it, And spirit to them that walk therein: I am the Lord: that is my name: And my glory will I not give to another, Neither my praise to graven images” (Isaiah 42:5, 8).
