In the 21st chapter, there seems to be a couple of threads of thought. One deals with those who are a false witness, which Solomon has much to say about in Provers. The other, which I will share a couple of brief thoughts about, is the subject of worship. And more than that, hollow, meaningless, evil worship.
Today, we often define worship and a song service, but it is much more than that. The two verse I want to point out to you are:
Proverbs 21:3 To do justice and judgment is more acceptable to the LORD than sacrifice.
Proverbs 21:27 The sacrifice of the wicked is abomination: how much more, when he bringeth it with a wicked mind?
Now, is God against sacrifice? No. But God is against sacrifice when the sacrifice is true worship of Him. How many Christians, pastors included, just go through the motions every Sunday, every Wednesday, every day, and never have any heart in their actions? It is God's desire for our heart right with Him first and foremost. Why? Because God knows that if our heart is focused on Him, everything else will be "brought up to speed." We often define our spiritual temperature based on what we do and do not do. But as Solomon points out to us, God wants our heart to be in it. Is yours?
