Read Joshua 18-19 and Jeremiah 9.
This devotional is about Jeremiah 9:23-24.
Remember a few days ago when God commanded the people not to say, “This is the temple of the Lord, the temple of the Lord, the temple of the Lord!” (7:4)? That chapter was about the spiritual pride of the people. Because they believed that God was in their city, they believed they were invincible.
This chapter is much sadder; tears recur throughout its verses. The pride of Judah would quickly flatten like air being let out of an inflated balloon as the Babylonians conquered the city of Jerusalem, despite “The temple of the Lord!” within its walls. This chapter prophesies of a judgment that was still future to Judah when it was given. God calls them to stop lying to themselves about their exceptionalism and get serious about their true spiritual condition. Sin ran through Judah like blood runs through your veins; yet God’s people were proud. Therefore, God promised them, “I will make Jerusalem a heap of ruins, a haunt of jackals; and I will lay waste the towns of Judah so no one can live there” (v. 11).
The only thing God allows us to be proud about is him. Verses 23-24 say, “This is what the Lord says: ‘Let not the wise boast of their wisdom or the strong boast of their strength or the rich boast of their riches, but let the one who boasts boast about this: that they have the understanding to know me….” But this is not pride in their intellect or insight; only God can give “understanding to know” him and he gives it according to his will, to those who are humble and repentant, by his grace.
Also, note that just slapping God’s name on your beliefs is nothing to be proud about. Instead, the proper boast of the believer is in the knowledge of God as he truly is. Verse 24c-f says, “‘that I am the Lord, who exercises kindness, justice and righteousness on earth, for in these I delight,’ declares the Lord.” Kindness is foreign to sinful hearts filled with hate. Justice and righteousness are foreign concepts to guilty sinners before a holy God. Only the grace of God can cause us to love and be proud of God as he really is. Once we know him, though, we have what we need to weather the problems of life, even if the strongholds we trust (“the temple of the Lord!”) are thrown down in front of us.
