Without Blemish

I wonder why the burnt offerings made unto God are without blemish. God is not served by human hands, as if he needed anything, because he himself gives all men life and breath and everything else.

Leviticus 22:19 you shall offer of your own free will a male without blemish from the cattle, from the sheep, or from the goats.

The offerings are to be eaten by the children of Aaron.

1 Corinthians 9:13 Do you not know that those who minister the holy things eat of the things of the temple, and those who serve at the altar partake of the offerings of the altar?

Leviticus 6:18 All the males among the children of Aaron may eat it. It shall be a statute forever in your generations concerning the offerings made by fire to the LORD. Everyone who touches them must be holy.

The offerings that comes from the good heart of the giver makes the children of Aaron holy or without blemish.

Matthew 23:19 Fools and blind! For which is greater, the gift or the altar that sanctifies the gift?

All these things happened to them as examples, and they were written for our admonition, upon whom the ends of the ages have come.

Matthew 5:23-24 Therefore if you bring your gift to the altar, and there remember that your brother has something against you, leave your gift there before the altar, and go your way. First be reconciled to your brother, and then come and offer your gift.

Live such good lives among the unbelievers that they may see your good deeds and glorify God.

Ephesians 2:10 For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand that we should walk in them.

The gifts, the giver, the recipient of the gifts must therefore be without blemish to become holy in the eyes of God.
