So it is that real, personal sacrifice never was placing an animal on the altar. Instead, it is a willingness to put the animal in us upon the altar and letting it be consumed! Such is the 'sacrifice unto the Lord... of a broken heart and a contrite spirit,' (D&C 59:8), a prerequisite to taking up the cross, while giving 'away all [our] sins' in order to 'know God' (Alma 22:18) for the denial of self precedes the full acceptance of Him.
