How did man approach God at the tabernacle?
Man approached God at the tabernacle by coming to the brazen altar, where sacrifices were made. The high priest alone entered once a year to the ark of the covenant and mercy seat to sprinkle. God's instructions began with Himself, showing that salvation starts with God, not man's initiative.
Les teaches that as man would approach God at the tabernacle, he had to come from the east side, where the brazen altar stood, and there sacrifices were made. The ark of the covenant and the mercy seat were in the back, and the high priest would come once a year and sprinkle. God began His instructions with the ark, not the altar, because when God deals with man in salvation, everything must begin with Himself. Man does not look for and find God; God takes the initiative.
