I wanted to clarify the purpose of the Tabernacle, and later the Temple, since many seem to be confused as to what it’s purpose was, and what it will be in the future when it is built again.
The purpose of the Temple is for G-d to dwell with man.
It was not to provide atonement for sin. That was not its function. Instead it is because we are unclean, and sinful, and G-d who is holy can not dwell with unclean and sinful man, that atonement for us is required as we “draw near” to G-d. In fact the Hebrew word for “drawing near” is the same as “making a sacrifice.”
