Lobbing hand grenades on the bride of Christ takes zero talent or effort. I also think this really takes God off. My five-year-old child complains and whines when things aren't the way she wants them, but courageous men and women roll up their sleeves and get busy. I want to be an active participant in putting back together the broken pieces.
The apprehension of this blessed truth (God's faithfulness) will check our murmurings. The Lord knows what is best for each of us, and one effect or resting on this truth will be the silencing of our petulant complainings. God is greatly honored when, under trial and chastening, we have good thoughts of Him, vindicate His wisdom and justice, and recognize His love in His very rebukes.
Children are grateful when Santa Claus puts in their stockings gifts of toys or sweets. Could I not be grateful to Santa Claus when he put in my stockings the gift of two miraculous legs? We thank people for birthday presents of cigars and slippers. Can I thank no onefor the birthday present of birth?
If you took one-tenth the energy you put into complaining and applied it to solving the problem, you'd be surprised by how well things can work out... Complaining does not work as a strategy. We all have finite time and energy. Any time we spend whining is unlikely to help us achieve our goals. And it won't make us happier.
