Commentaries:
From this direct response of Jesus, we can see that God expects each person to take personal responsibility in responding to the events of his own life and not to look with envy, bitterness, or self-righteousness at what He requires of others. Each must learn to operate within his faith. God deals with each of us individually, preparing us for what He wants for His Kingdom. In a context that applies to the entire nation of Israel among all other peoples of the earth, Deuteronomy 8:18 contains an element of this same principle: "And you shall remember the Lord your God, for it is He who gives you power to get wealth, that He may establish His covenant which He swore to your fathers, as it is this day."
