If you sin harder do you need to work harder to get to heaven?
Jesus told this story, related in the Gospel according to Lukein chapter 18: 9To some who were confident of their own righteousness and looked down on everybody else, Jesus told this parable: 10"Two men went up to the temple to pray, one a Pharisee and the other a tax collector. 11The Pharisee stood up and prayed about[a] himself: āGod, I thank you that I am not like other menārobbers, evildoers, adulterersāor even like this tax collector. 12I fast twice a week and give a tenth of all I get.ā
13"But the tax collector stood at a distance. He would not even look up to heaven, but beat his breast and said, āGod, have mercy on me, a sinner.ā
14"I tell you that this man, rather than the other, went home justified before God. For everyone who exalts himself will be humbled, and he who humbles himself will be exalted."
This story shows that there is actually an advantage to knowing clearly that one is a sinner. (Everybody is a sinner, but some of us are more aware of it.) We approach God knowing how greatly we depend on his mercy. We know that we are not capable of being saved through our own efforts. We humble ourselves before God who loves us and wants to help us.
We do need to work on overcoming our sins. We have to do our best to fight our impulses toward evil. But God still loves us when we fail and forgives us and gives us strength to keep trying.
One of the best things about being Catholic is the Sacrament of Confession. The priest acts in the person of Christ so that we can actually hear Godās words of forgiveness to us and know that we have been pardoned. Also, the Sacrament gives us Grace which strengthens us to resist our tendencies to sin.
