The first instance of worship was an animal slaughtered and sacrificed upon an altar. (Genesis 4.4). There was no music, no choir and no shouts of praise; just shaky blood-stained hands, and a carcass dead on an altar. But what it meant was substitution; the worshipper was saying to God, “I offer this as myself.” The Hebrew word for sacrifice is Holo (from where we get the word Holocaust) and literally means slaughter; something that has been killed and offered to God. It couldn’t be used for anything but to be consumed in the crackling fire. Moses tabernacle contained some horrible sights; blood, knives, searing meat, smoke and cattle standing around to be killed, but David changed all that. David realised God would rather have the whole heart of a living man offered to Him (a living sacrifice) than the lifeless carcass of a bull or a goat. For You do not desire sacrifice, or else I would give it; You do not delight in burnt offering. The sacrifices of God are a broken spirit, A broken and a contrite heart— These, O God, You will not despise. Psalms 51:15-16 Worship is placing ourselves “upon the altar” as a willing offering to God; it is the sacrificing of our lives to the one who is worthy (Romans 12.1). It is not necessarily musical in anyway. Unlike praise you can’t see or hear worship. Worship is an attitude toward God, in the heart and spirit of a person.
Friend, we can come to church, sing, and shout praise God but if there is no complete surrender, we haven’t worshipped. Only God can see worship and it is our worship that ratifies our praise.
