for a reason

"Wherein lies the difference between those who are in the family of God and others? In two vital ways the difference lies. First in His Fatherly interest and control. We have obeyed the commandment: 'Come out from among them... and I will receive you and will be a Father unto you, and ye shall be my sons and daughters, saith the Lord Almighty.' To such 'the exhortation speaketh'. 'My son, despise not thou the chastening of the Lord, nor faitnt when thou art rebuked of him: for whom the Lord loveth He chasteneth, and scourgeth every son whom He receieveth.' And further, He chastens us for our profit, that we might be partakers of His holiness."
