God mocks the pagan idols for being blind, deaf, and nasally challenged:
Their idols are silver and gold,
The work of men’s hands.
They have mouths, but they do not speak
Eyes they have, but they do not see
They have ears, but they do not hear
Noses they have, but they do not smell
But our God is the Living God.
He can see, He can hear, and He can smell:
Noah built an altar to the Lord, and took of every clean animal and of every clean bird, and offered burnt offerings on the altar. And the Lord smelled a soothing aroma. (Genesis 8:20-21)
He shall take from it his handful of the fine flour of the grain offering, with its oil, and all the frankincense which is on the grain offering, and shall burn it on the altar for a sweet aroma, as a memorial to the Lord. (Leviticus 6:15)
When we sing during worship, we are not just singing to ourselves.
We sing because God hears us.
When we bow, when we pray, when we lift our hands in worship,
We are not just going through the motions for ourselves.
We worship this way because God sees us.
The Church has been worshiping with incense for 2000 years,
and not merely because it smells good to us.
We offer incense because it smells good to Him.
