Jesus' own witness of sacrificial love and forgiveness, and his work to heal the sick and care for those in need, represent God's ways and vision for us.
We should never forget that God granted us the power to reason so that we would do His work here on Earth - so that we would use science to cure disease, and heal the sick, and save lives.
I'm very blessed that I have a healthy temper. I can become quite angry and burning in anger, but I have never been bitter. Bitterness is a corrosive, terrible acid. It just eats you and makes you sick.
