When Christ is called, “Good Master,” He responds, “Why do you call me good? There is none good but one, that is God.” (Mk 10:17-18) This is helpful: God is good, and only God is good.
So, Man is not good; Man is bad. Man has free will: God gives Man freedom to choose, and in choosing freely Man always chooses badly. (Ge 6:5)
God can make us good, and only God can make us good. If He can make anyone good, then He can make you and me good, by replicating His nature in us.
Do we want to be good? This is the beginning of goodness, itself the gift of God, working in us both to will and to do of His good pleasure. (Php 2:13)
I seem to need a constant reminder that my hope is not in politics, or in religion, or in my family, my friends, my job or my country … or in myself … but in a sovereign God Who always does according to His own purpose and will … which is always good. (Ep 1:11)
