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.
Capital punishment is not confined to the Old Testament and is not done to the exclusion of God’s grace, but rather as an act of God’s just judgment.
