Jeremiah 16:10b ‘Why has the Lord pronounced all this great evil against us? What is our iniquity? What is the sin that we have committed against the Lord our God?’
Sin is blinding. Eventually, sin blinds us to much, we don't even notice our sin anymore. We, like the Israelites, are grossly mistaken when we presume that God's patience in delaying judgment means that judgment will not come at all. The Word is clear, eventually God's patience will end and judgment will come - for us, just like it did for the people of Judah, and the people of Israel before them.
Jeremiah 17:7-8 “Blessed is the man who trusts in the Lord, whose trust is the Lord. He is like a tree planted by water, that sends out its roots by the stream, and does not fear when heat comes, for its leaves remain green, and is not anxious in the year of drought, for it does not cease to bear fruit.”
This passage is very similar to Psalm 1:3
When we meditate on God's word and apply His wisdom, we will bear good fruit - actions and attitudes that honour and glorify God.
This does not come naturally.....
Jeremiah 17:9-10 The heart is deceitful above all things, and desperately sick; who can understand it? “I the Lord search the heart and test the mind, to give every man according to his ways, according to the fruit of his deeds.”
