"My son, do not make light of the Lord's discipline, and do not lose heart when he rebukes you, because the Lord disciplines those he loves, and he punishes everyone he accepts as a son. Endure hardship as discipline; God is treating you as sons. For what son is not disciplined by his father? If you are not disciplined (and everyone undergoes discipline), then you are illegitimate children and not true sons. Moreover, we have all had human fathers who disciplined us and we respected them for it. How much more should we submit to the Father of our spirits and live! Our fathers disciplined us for a little while as they thought best; but God disciplines us for our good, that we may share in his holiness. No discipline seems pleasant at the time, but painful. Later on, however, it produces a harvest of righteousness and peace for those who have been trained by it."
It may be difficult to believe, but discipline is an example of love. If you are like me, when discipline comes my way I am not feeling very loved. However, if we are to believe the above verses, then we come to know God the Father as one who "disciplines those he loves." Not only that, the scripture lets us know that God "punishes everyone he accepts as a son."
Most of the time when we think of discipline, we think in terms of parent's role to discipline their children. The Bible does address that and there are verses to support the concept of parental discipline.
Proverbs 13:24, TLB. "If you refuse to discipline your son, it proves you don't love him; for if you love him, you will be prompt to punish him."
Proverbs 19:18, TLB. "Discipline your son in his early years while there is hope. If you don't you will ruin his life."
Certainly the discipline of children is a responsibility parents cannot deny nor avoid. As parents we understand these actions are based on our love for children as they learn and mature. And remember, the Bible says if we don't discipline our children we will be responsible for ruining their lives.
In like manner, God administers his discipline on his children, and it is always for their own good. While discipline hurts, we are encouraged to accept it because it is God treating us as sons. It becomes easy to understand if God withholds his discipline, we are like the child from the Proverbs, and our lives will be ruined.
Look at it like this, if God loves you enough to give his Son to die for you, then he loves you enough to discipline you. Here is the good part. The scripture from Hebrews assures us that God's discipline is for "our good, that we may share in his holiness." And then," Later on, however, it produces a harvest of righteousness and peace for those who have been trained by it."
