Ps 141:2 As incense--the evening sacrifice; sweet incense was burned every morning and evening on the altar of incense. Ex 30:7-8 The evening sacrifice was, like the morning sacrifice, which it seems here to include, a daily offering. The psalmist beseeches God that his prayer may be like the daily incense and offering, in both permanency and acceptableness. It was an ordinance of the Levitical law, that sweet incense and sacrifices should be offered every morning and evening. By this God teaches us that we should worship him daily and at stated seasons; and that our prayers, offered through faith in the atonement of his Son, are fragrant and pleasant to him, like the incense offered by Aaron and his sons.
~Family Bible Notes
Smell goods! Mm-mm, aren't they nice? I received some handmade soaps and a Yankee candle for Christmas from two of my daughter- in-laws. I just love them! As I was thinking about and enjoying the sweet smells from these gifts, I was reminded of sweet incense that was offered to the Lord. Family Bible Notes defines this well:
Every time I smell one of these items I want to remind myself that I need to spend quite time each day worshiping the Lord and praying to Him. This is sweet smelling and pleasant to Him.
If you Know Him you are entitled to come boldly to the throne of grace and offer your prayers to Him.
