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.
One might think that prayer has always existed in the exact manner in which it presently exists, but such is not the case. It appears that the first major shift in prayer took place in Genesis 4:26. We know that Adam and Eve freely spoke with the Lord face-to-face in the garden (Genesis 3:8). However, it seems that the fall of man caused men to have to begin “to call upon the name of the LORD.” Even then, prayer was not as it is today. The very fact that prayer has not always existed parallels a time in the future when prayer as we know it will not exist. When man had full access to the Lord, there was no need for prayer. In eternity, the same will be true. For now, the Lord has given us access to Him through prayer (Hebrews 4:16).
