Disciple of God

The characteristic of a disciple is not that he does good things, but he is good in his motives, having been made good by the supernatural grace of God

Whatever that is not of God is not good which is evil. Only God is good. Human defination of goodness is different from God's goodness. The way human define goodness changes, but the way God define goodness never change.

Human's defination of goodness = people are happy with what you do and they benefit from it
God's defination of goodness = walking in God's way.
