The Christian up to his eyes in trouble can take comfort from the knowledge that in God's kindly plan it all has a positive purpose, to further his sanctification. In this world, royal children have to undergo extra training and discipline which other children escape, in order to fit them for their high destiny. it is the same with the children of the King of kings. The clue to understanding all his dealings with them is to remember that throughout their lives he is training them for what awaits them, and chiseling them into the image of Christ. Sometimes the chiseling process is painful and the discipline irksome, but then the scripture reminds us: (Heb 12: 6-7, 11)
