Do you wrestle with a habitual sin? Something you just can't seem to get past? Maybe it's sexual sin, or a short temper, or anxiety over your finances or future. The good news is we're not alone. In this Sunday's passage, the great, faithful patriarch Abraham blows it again. It's déjà vu from chapter 12. Even though he is decades older and has had numerous personal encounters with God, Abraham falls into the same old sins. In God's word this Sunday, we'll find encouragement and hope for overcoming our habitual sins. But most of all: grace.
