Answer: ''We are creatures of the same God. We must therefore love all as children of God even though they are doing us harm. Christ loved his persecutors. It is possible for us to attain to that love. God manifested his love by creating man in His own image. Man must manifest his love by developing himself and others more and more in the image of God. The true fruit of man is, therefore, love. The purpose of a tree is to produce fruit. Man is like a tree; his fruit should be love."
