God is as just as He is merciful. Think of a parent. A parent will admonish a child, and rightfully so, if the child is doing wrong. A parent does this out of love.
Teachers do the same. They correct students to make an example so other students will not err as has that one student.
Let’s face it, if people did not have any sort of correction for evil-doing, would most people change their ways? Certainly not! It’s like spoiled brats, if God gave everyone everything they wanted and wanted nothing in return, people would become stuck in their ways. God, instead, wants people to seek to become holy. Love is not being kind and willfully allowing evil, accepting everything anyone does. That is not love.
As you probably know, in Sodom and Gomorrah, God gave people a chance to repent repeatedly. Many, many chances. These people were extremely perverse. God wanted to protect Abraham from these people who would not listen, but he also wanted to teach lesson on his Truth to Abraham.
God did not destroy Sodom and Gomorrah without trying to warn the people. He gave them chance after chance to repent. In fact, God was infinitely merciful to them for their grave transgressions, but he is also infinitely just.
God could wipe us all off of the planet. Jesus died a terrible, terrible death out of love for us. God gives us all chances to change and gives us the grace to do so, if we but seek Him.
People who think of God as only Just, do not recognize his great Mercy. God has incredible mercy, more than that of anyone who has ever lived. Infinitely more than Our Lady, the angels, all humanity, things seen and unseen combined.
To those people, you have to personalize it, I believe. If you had a friend who slapped you in the face for no reason, you might forgive him the first time if he apologized, saying he wouldn’t do it again, right? Some people would.
What if, right after he apologized, saying he wouldn’t do it again, and your forgave him, he slapped you again? Would you forgive him again if he asked for forgiveness? Few people would.
What if the next day he did it a third time, and apologized, saying he would never do it again? Most people would not want to forgive after a while…and yet, God forgives us if we truly say we are sorry and repent, even though we effectively slap him, but far worse, each time we sin.
I really enjoy the talk Fr. Larry Richards gave on Confession for Catholic Lighthouse Media CDs. It explains mercy in a down to earth way, which even the most hardened person would understand. I actually played it for a person who was away from confession, because she believed God should not forgive her because He should be angry with her. She listened to it and went to confession.
