We could go on. Do we show hospitality without grumbling (1 Peter 4:9)? Most of us have enough social tact to avoid grumbling at guests, but do you harbor resentment and bitterness toward your husband (or wife) or your kids because of all of your labor? Do you have an edge about you? Do you find yourself thinking, Nobody appreciates all that I do. Nobody appreciates how many details I manage, how much time I spend trying to make everything special?
Of course, this isn’t to excuse ingratitude and selfishness in others. But we may not use the failures of others to justify our own disobedience. A difference exists between addressing sin and grumbling about unaddressed sin. And a difference exists between addressing sin directly and passive-aggressively murmuring about sin. Do we do all things without grumbling and complaining?
In the end, we remember a simple truth: God loves a cheerful giver, not a grumbler. He loves cheerful obedience, not murmuring and complaining obedience. Such obedience, especially when things are hard, signals God’s grace to us, a sign that he is at work within us to produce an obedience that shines, an obedience that makes apostles proud and God happy. So as you obey, do so all the way, right away, with a happy heart.
