We cannot deceive God. Twice in the Acts God is called “the Heartknower” (Acts 1:24; 15:8). But we can deceive ourselves. Here are four differences between deceit and honesty in our hearts. One, a deceitful heart doesn’t know its sin because it doesn’t want to know. But an honest heart is saying, “Bring it on.” Two, a deceitful heart notices how well a sermon applies to someone else. But an honest heart is too concerned about itself to judge another. Three, a deceitful heart, when it isn’t growing, blames its inertia on hardship or its church or even on God himself. But an honest heart says, “It’s my fault. I need to get in gear.” Four, a deceitful heart delays response. It says, “I’ll get around to it, even soon. But I can’t right now.” An honest heart puts God first. Delayed obedience is a way of saying, “I’m setting the terms. I am Lord.” But an honest heart says, “Lord, whatever you want – right now.” An honest heart says, with the old hymn, 'The dearest idol I have known, whate’er that idol be, help me to tear it from Thy throne and worship only Thee.'
