Heidelberg 112: Your Speech Shall Accord With Objective Reality

Heidelberg 110–111: You Shall Not Steal

The eighth commandment says: “You shall not steal” (Exod 20:15). I recall following Mom down the grocery aisle and picking grapes as a I went. I was probably 5 or 6. I saw the grapes. They looked good and I wanted some. . . . Continue reading →

Heidelberg 108–109: You Were Bought With A Price (2)
