Discipline

Discipline says, "I'll teach you how to do it right,"
While punishment says, "I'll make you regret doing it wrong"

This reminds me of this quote

A large crowd followed the Savior as He ministered by the shore of the Sea of Galilee. So that more could hear Him, He got into Peter’s fishing boat and asked to be taken a little way out from the shore. After He had finished speaking, He told Peter, who had fished all night without success, to go out in the lake and let down his nets in the deep water. Peter obeyed, and he caught so many fish that the nets broke. Peter called to his partners, James and John, to come and help. All were amazed at the number of fish that were caught. Jesus said to Peter, “Fear not; from henceforth thou shalt catch men.” Luke then tells us, “When they had brought their ships to land, they forsook all, and followed him.”1 They became the Lord’s disciples. 

The word for disciple and the word for discipline both come from the same Latin root—discipulus, which means pupil. It emphasizes practice or exercise. Self-discipline and self-control are consistent and permanent characteristics of the followers of Jesus, as exemplified by Peter, James, and John, who indeed “forsook all, and followed him.” 

What is discipleship? It is primarily obedience to the Savior. Discipleship includes many things. It is chastity. It is tithing. It is family home evening. It is keeping all the commandments. It is forsaking anything that is not good for us. Everything in life has a price. Considering the Savior’s great promise for peace in this life and eternal life in the life to come, discipleship is a price worth paying. It is a price we cannot afford not to pay. By measure, the requirements of discipleship are much, much less than the promised blessings. ("Discipleship", James E. Faust, Oct 2006 General Conference)
