When you push through to a new layer of achievement through discipline. You discover that which at one time seemed impossible, to now be commonplace.
Habits of discipline reinforce themselves into greater habits of discipline. Unfortunately, the converse is also true.
Increased discipline, self-control & focus, which seems drudgery can become pleasant; when you teach yourself to enjoy what’s good for you!
God so constructed our behavior patterns that good habits can form chain’s of improved action & increased well-being. That which is good for us can also become that which we enjoy doing. It really has to do with the joy of obedience.
God has built it in our warp and woof, to feel good, about doing good.
