The Book of Proverbs is many things, but subtle is not one of them. It calls us clearly and boldly to live in alignment with the grain of God’s universe. Central to that call is wisdom’s repeated warning: guard your heart. The heart is not neutral ground—it is embattled territory—and God calls His people to active vigilance. This week, we’ll explore how guarding the heart is both an invitation to wisdom and a gracious warning meant to protect our lives.
