What the Bible says about Dedicated to God
(From Forerunner Commentary)
A life is offered. This distinction is quite significant once we understand that this offering typifies devotion and that this offering does not picture sin or the death of the offerer. In the offerings of Leviticus, a sacrifice is primarily perceived as a gift to God. Jesus uses the word "corban" in Mark 7:11. Corban itself means "gift" or "dedicated to God," and its root means "to bring near." Recall that the offerer is to lay his hand on the animal before it is killed to signify that the animal represents the offerer giving himself. Therefore, the killing of the animal represents the offerer bringing himself near, making a gift of himself, devoting his entire life to God. It indicates he holds nothing back.
