The heart of Jesus will only begin to develop in our lives as the Holy Spirit causes His fruit to grow within us. Would you say that you are someone who is faithful? Can those around you depend on you, can they trust you, are you reliable? Would God consider you as someone who is faithful?
We see enough bitterness and wrath and anger and clamor (shouting) and slander in our world today, not to mention the physical, mental and emotional injury which goes along with it. We who are Christians are to have no part in such things. Instead, we should be known as those who are kind to one another, tenderhearted, forgiving each other.
