Hebrews 7:11 If perfection could have been attained through the Levitical priesthood – and indeed the law given to the people established that priesthood – why was there still need for another priest to come, one in the order of Melchizedek, not in the order of Aaron?
Jesus came because we needed to break free from the loop of having to offer sacrifices all the time for everything we do wrong.
Priests would have to offer sacrifices to cleanse themselves before they could offer sacrifices for others because they too have sinned.
Jesus offered Himself, sinless and perfect, to be the ultimate and final sacrifice for us all and for ever!
