For once I have to agree with the Pope. If one really think they're incapable of resisting sin then simply try to live a perfect life.
The day I met Christ was the day I realized that I was a sinful creature.
Correction-If one really think they're CAPABLE of resisting sin then simply try to live a perfect life.
One difference between a non-Christian and Christian is that non-Christians realize they sin but don't care because to them it doesn't matter. Christians know they sin and know that it does matter.
