|An offering of Thanks and Praise|
In the Old Testament incense were required for several offerings to God. It is one area that is not used in worship of God as much in the modern age. I have been in a Catholic church when the priest waves and incense over the people. But to me that seems more like a blessing of the people and not offering the incense up to God. It was often added to the grain offerings to be a sweet aroma to God during the sacrificial process.
