Between AD 63-67, the apostle Peter was inspired to write to the "elect" who were dispersed throughout Asia Minor—and to us today—that Christians are to offer up spiritual sacrifices and proclaim the praises of God. We are in training now, learning how to be priests of God for His spiritual priesthood, and a primary reason is to offer up spiritual sacrifices. A spiritual sacrifice is an act of giving up and offering to God our time and effort in a way that is pleasing to Him.

What makes a spiritual sacrifice acceptable to God? Is it merely the sacrificing of our time and effort? No, it is more than that. Comparing the sacrifice of Noah to the hypocritical sacrifices of the children of Israel shows that the attitude and righteousness of the offerer is important to God (Genesis 8:20-21; Amos 5:21-27). A spiritual sacrifice must be offered in an attitude of obedience, humility, and reverence.
