Keep your heart with all diligence.
—Proverbs 4:23
The Israelites were an erratic bunch: singing at the tops of their voices when they crossed the Red Sea without getting mud on their sandals, and bellyaching three days later about bitter water (Ex 15).
When Moses started his hike up Sinai, they promised: “We will do everything the Lord has said” (Ex 24:7). But a forty-day wait for Moses’ return was too long: “They rejected him and in their hearts turned back to Egypt” (Acts 7:39).
In their hearts, they turned back—then began pressuring Aaron to make them a god to lead them back to Egypt.
Sin begins in the heart before culminating in the act. A crash-landing in sin city gets its start in the heart.
“Above all else, guard your heart, for it affects everything you do” (Prv 4:23).
You’re vulnerable in sin city.
Better to stay home and clean up the place.
