True strength is not shown in what you can move or what you can pick up but in what you resist. Restraint is having total power under complete control. We fail at many things ( diets, finances, marriage, work and our Spiritual walk) because of the lack of restraint. A constant show of strength is actually a lack of strength. It takes more strength to restrain yourself than it takes to just do it. This is confirmed in the Bible, in the list of the fruit of the Spirit you'll see self CONTROL. So practice restraint as a show of Strength under complete control.
