. . . All these examples point up to a grave modern evil, permitting temporal consequences to decide eternal issues. A word of caution should be added. Sometimes an act, though good in itself, may, in a given set of circumstances, be better held in abeyance. Only be sure the reason for waiting is the desire to promote the glory of God and bless mankind. Sometimes a word, though true, would be out of season and injurious to someone. Better be silent than to speak a harmful word. Only let the reason for silence be love and not fear.
To sum up: no act, however noble it may seem to be, done from fear of consequences can be good in itself. A good deed done for earthly gain is an evil deed at bottom. Motive imparts moral quality, and without a holy motive there cannot be a holy act.
