After we have overcome our faults, we can never be sure when will they arose or flare up again and make us offend God. We must try to face situations in which we can practice Virtues opposed to our faults. For those who are impatient, you should look for opportunities to practice Patience. So too with your other faults you have. Only action will prove what faults we have and which Virtues we need. A man who is afraid of inconvinience or suffering will never advance in virtue. He lacks the courage to face the unpleasant situation which can strengthen his virtue. We must face those unpleasant situations like suffering from illness, poverty and more and must deal with them As God want us to do. While Dealing with those situations, we should be unselfish, or humble, or patient and should not fear to suffer as God is always with us every now and then. Remember that Jesus choose to suffer and sacrifice to pay for our sins.
