Jeremiah 48:10 The one who does the Lord’s business deceitfully is cursed…
God threatens those He called to destroy Moab with a curse if they were lax in their duties. If they didn’t bring about Moab’s complete destruction, they would be cursed.
I think this a great verse to apply to the army of thieves, false prophets and wolves we see in some parts of the church today. Cursed are those who do the Lord’s work deceitfully.
In Leviticus 10 Nadab and Abihu brought ‘Strange Fire’ to the Lord. The word in Hebrew means ‘unauthorized’. They were enthusiastic but what they did was not according to Scripture. They had devised a new ceremony for worshiping Jehovah, but He would not accept it. And they paid a heavy price for their presumption.
Why did they sin? We can’t know for sure but what they did is an example of ‘will worship’, doing what seems good at the moment (Col. 2:23). This is a warning to all of us. Carnal enthusiasm and willful self-indulgence are no substitute for the fullness of the Spirit, and one of the fruits of the Spirit is self-control (Gal. 5:23).
When we worship God we need to make sure that what we do is truly pleasing to Him according to His word and not just something that makes us feel good.
