We understand this as Christians. But I must come to Him. When a child is rebellious, he is disciplined. When God's people are rebellious, God disciplines. It is not because He hates us, but because He loves us.
Sin is a corrupting, killing, foreign substance in the soul of the individual and the church.
The hurt cannot be healed until the cause of it is removed. Repentance and a return to God is the answer. But this message is cleverly drowned out today with campaigns and programs and religious retreats and dynamic workshops. It is unpopular to call people to repentance. Unholy people want to preserve the status quo.
