How do you smell? Do you stink? Leviticus 1-3

Leviticus 1:9 (NASBStr)

Its entrails, however, and its legs he shall wash with water. And the priest shall offer up in smoke all of it on the altar for a burnt offering, an offering by fire of a soothing aroma to the Lord.

The english word, in the NASB, aroma is used 47 times.  I has a variety of meanings but typically what you think; a good smell.  When the priest offered a sacrifice for the Israelite and it was presented in the right way and offered in the right way, the smell to God was a soothing aroma.   Paul might have been reading this passage prior to his writing the following:

2 Corinthians 2:14-15 (NASBStr)

But thanks be to God, who always leads us in triumph in Christ, and manifests through us the sweet aroma of the knowledge of Him in every place. For we are a fragrance of Christ to God among those who are being saved and among those who are perishing;

We no longer offer a lamb from our flocks to find acceptance to God.  God offered a lamb from His flock of One, His Son, for our sin.   That Lamb was without blemish.   That Lamb was the sweet aroma God needs to forgive our sins.  However, through faith, He comes into our lives, through the ministry of the Spirit, and becomes a sweet aroma both TO God and FOR God.   We can't be an acceptable offering to God.  It is only through the ministry of the Spirit that God can and does produce in us an aroma He can tolerate and He can use.   God is the God of a sweet aroma.     He is the only one who can clean up our stink.   We the lamb full of blemish and could never qualify to be offered on the alter.   It is only though God's Son that we can be a sweet aroma for God.   His substitutioninary atonement provides His Son to be the sweet aroma for our lives.
