Hebrews 12:8-10

If you are never disciplined (and every child must be disciplined), you are not true children. We have all had fathers here on earth who disciplined us, and we respected them. So it is even more important that we accept discipline from the Father of our spirits so we will have life. Our fathers on earth disciplined us for a short time in the way they thought was best. But God disciplines us to help us, so we can become holy as he is.
