No one wants to be called a hypocrite. But if we don't practice what we preach, we become living and breathing billboards for hypocrisy. Study out in the Bible the things you want to change in your character, such as selfishness, greed or impatience. Religious bookstores also offer some excellent character-building books. Set an example in love.
Love seems like such a rare thing today.
True love requires the ability to forgive, because some imperfect person is always going to do something or another that will hurt you. A good way to forgive is to put yourself in the offender's shoes or try to understand why the offender acts the way he or she does. I've learned that some of the meanest people I've encountered have suffered even meaner lives. It is easy to forgive someone you empathize with or feel sympathy for. Set an example in faith.
