God wants his goodness, he wants us to share the goodness of God to the world.
Of course.
We should do good, we should not be tired of doing good as long as we have the ability. It's not about what we do, it's about our abilities, what we do. When we are talking about this ability, this is how we give to someone as much as we have that ability.
God must show love to one another. Even though they are not a family muscle, they are outside our faith. You cannot help everyone, but you can try as much as you can to be of help to one or two people. It commands God that we do good to others.
Let us walk with love because it's because of Jesus that commanded us to do so good. Doing good should not be limited to our relatives. We should extend our good works. We should all be good to all men.
