In the Old Testament, people had to make animal sacrifices as payment for their sins, with Scripture telling us that the aroma of the sacrifice was pleasing to God. When Jesus died on the cross for us, God no longer smelled the sacrifice -- He tasted it Himself when He gave up His only Son as payment for our sins. Because of that gift, we can experience true relationship with Him -- but we'll never understand the full goodness of God unless we taste it ourselves.
