People's motives in serving Christ vary from pure to sinful. However, other men’s motives should not rob us of the joy of Jesus Christ being preached.
Strength is not tested or demonstrated during times of ease. Rather, it is during times of adversity that one finds out just how strong he is.
God has a calling on each man’s life. Furthermore, He enables men to fulfill their appointed work. Man, however, must be strong and DO the work.
