“And Nadab and Abihu, the sons of Aaron, took either of them his censer, and put fire therein, and put incense thereon, and offered strange fire before the LORD, which he commanded them not. ²And there went out fire from the LORD, and devoured them, and they died before the LORD. ³Then Moses said unto Aaron, This is it that the LORD spake, saying, I will be sanctified in them that come nigh me, and before all the people I will be glorified. And Aaron held his peace.” Leviticus 10:1-3

Christians are so willing to sing songs about the holiness of God. However, if they are not living holy lives, is it any different than Nadab and Abihu? Lord, help us to walk holy before we ever sing about holiness.
