Joy is better than happiness. Joy is the presence of God working within you. Sometimes you feel it at your lowest ebb. It literally saves you and is transforming.
Happiness is unreliable and relative. Nice when you have it but elusive when you need it.
The next time you go to anger with a person, try telling them you love them or embrace them. It will catch you off-guard and catch them before they fall.
It can’t hurt, and if you pay attention you will feel the Creator working in your heart.
