God is Just!
"God is, in other words, like a judge who as a private individual adheres to the law of society, and in this official capacity administers that same law, applying it to others. Scripture makes clear that sin has definite consequences, which must eventually come to pass, whether sooner or later. In Genesis 2:17, we read God's warning to Adam and Eve: 'You must not eat from the tree of the knowledge of good and evil, for when you eat of it you will surely die.' Similar warnings recur throughout Scripture, including Paul's statement that 'the wages of sin is death' (Rom. 6:23). God will punish sin, for sin intrinsically deserves to be punished. It disrupts the very structure of the divine spiritual; economy, and this disruption or imbalance must necessarily be set right. Not only evil, but good as well will ultimately receive its rewards."
