But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control. Against such things there is no law. — Galatians 5:22,23
Meekness isn't weakness—it's power under control, the fruit of the spirit. Look at Christ: he could have called ten thousand angels, yet he did not open his mouth; the meek inherit the earth because they've learned from the one who is gentle and lowly in heart. This isn't natural to us—it's supernatural, worked in us by the spirit.
