GENESIS 8

After Noah and his family left the ark, Noah sacrificed some animals to the Lord.
Verse 21 says it was "a pleasing odor" to God, and the Amplified Bible adds that
it was "a scent of satisfaction to His heart."

Does God like the smell of blood? Does He like the smell of flesh in the fire?
Was that what was so satisfying to God? No. The thing that was pleasing to God
was that Noah prepared a sacrifice. Noah’s attitude toward God prompted him to
do what he thought would be pleasing to the Lord. It was a sign of relationship,
an act of gratitude.
