A practical definition for gentleness might be: "A Spirit-inspired lifestyle that responds in a calm, caring, and controlled manner."
Opposites of this word would be: harsh, mean, rude, callous, and merciless.
One writer described gentleness by saying it is like a set of shock absorbers, springs, and struts on a car. If gentleness is lacking, we are jarred, become sore, bruise easily, suffer damage, and even find ourselves in dangerous situations.
Evidence of gentleness is seen in our response to people and life in general. Do we see and treat people differently? As though we are Jesus, and as though they are Jesus!
