Once we are saved, we are to repent - that is, turn away from those things that cause us to sin. However, we still are imperfect humans and will do things that aren't Christlike. We still will have consequences to face for our sinning. The Holy Spirit causes us to feel guilt (conviction). The Christian who is sincere will continue to pray for forgiveness and ask God's help in repenting. A sincere Christian will do alot of soul-searching and self-examination. Just because Christians don't advertise and explain their shortcomings daily to the world doesn't mean they are hypocrits. Like someone else on this thread said, if we were perfect, we wouldn't need a savior. A Christian's duty when he sins and hurts another is to make amends with his brother and to ask God for forgiveness and help. We are also to forgive one another as God has forgiven us.
However, forgiveness is a whole other thread - a very misunderstood concept. A topic for a new day when we are all refreshed.
Amen...
