Since God is the rightful recipient of man’s sacrifices, then, by necessity, He is the only One who can rightfully provide the rules for the administration of the sacrifices. In the Old Testament, God established rules about the place (Joshua 22:29) and purity (Malachi 1:8, 14) of man’s sacrifices. Men who violated these rules, choosing rather to adopt their own rules of sacrifice and worship, often suffered harsh consequences, including death. The sacrifice of Christ for sin has changed many details of God’s demands for sacrifice; it has not, however, changed the fact that man must do things God’s way. God’s rules for sacrifice whether performed in the past, present, or future are to be dictated by scripture.
Many people fail to enjoy the present blessings by worrying about the inevitability of future difficulties. Though each time of life is certainly filled with its difficulties, it is also filled with tremendous opportunities for blessing. When young, a person ought to rejoice in his youth while keeping in mind that God will bring his deeds into judgment. When growing older, people ought to rejoice in getting married, having children, working, and serving the Lord. As one grows older, he can enjoy the benefits of each phase of life knowing that God has special blessings in store for each day. After all, why be robbed of today’s joys by worry concerning troubles and sorrows that may never come to pass? And if they do transpire, effort spent in worrying about them was useless.
