Leviticus 1 describes the ‘burnt offering’ that God formally established with Israel when He inaugurated the tabernacle or tent of meeting.
The burnt offering is a thanksgiving offering, was offered in the morning and evening and was wholly consumed meaning it was an offering for the entirety of the offerer.
There was an atoning element but it was not offered for specific sins but an offering based on gratitude to God.
In the same way Jesus Christ is our ongoing burnt offering. A whole, complete offering that represents our continued gratitude to God.
God communicated to man through the command to offer sacrifices; thus man worshipped and communicated to God through his offerings.
This phenomena is symbolized in our continual coming to God in the name of His Son Jesus Christ who represents to God our gratitude and complete redemption.
