Do you have a gentle spirit? Gentleness isn't a respected virtue in our culture, especially among men. The phrase, "Kill 'em all; let God sort 'em out" used to be a caricature of the most vile type of person that might exist. But these days, it has become far too common to immediately drop any efforts of gentleness, courtesy, or respect the moment we realize someone has a different point of view than our own. In news and politics, calls for imprisonment or even death over minor disagreements are not just common, but cheered on.
Biblical gentleness means to treat others as those for whom God has extra love and special concern. And our God has that extra love and special concern for every human in His creation; not just the people you like, not just the people you agree with, not just the people who think or act or look the same way as you. A gentle person approaches every interaction knowing that this moment might be when God uses you to bring another brother or sister into His kingdom.
Fred "Mister" Rogers used to say, "I'm so convinced that the space between the television set and the viewer is holy ground," meaning that any moment he was on screen might be a moment the Holy Spirit used him to minister to someone's life, and he approached every on screen moment with that attitude. When we treat others harshly or callously, we deny the Spirit the opportunity to work through us.
Gentleness is a fruit of the Spirit: something that God brings forth in you when you are allowing yourself to be led by Him. If you find yourself acting harshly or rough with others, it is a symptom of living by the flesh. When acting this way, you may find yourself using the excuse, "That's just how I was raised," or, "That's how people from [my cultural heritage] are." But now you are a new creation and a citizen of a new kingdom; from now on, gentleness is how your people behave.
If you find yourself frequently resorting to yelling, arguing, sarcasm, gesturing, or laying on your car horn, gentleness may be a fruit you need to meditate on and ask God to grow within you.
