VerseD: Jeremiah 17:9
The heart is deceitful above all things, and desperately sick; who can understand it?
Jeremiah 17:9, ESV
If we “look deep within” ourselves to find happiness, we will only be disappointed. Maybe this life will turn out better from “following our hearts,” but ultimately it usually leads us away from Christ and eternal life.
We should expect those outside of Christ to act unwisely and foolishly, but we should be sober-minded and seek His wisdom.
