“That's part of Jesus' point, that we all have sin in us. But he was also saying that sin begins and ends with the heart. Actually, that idea runs throughout the entire Bible. As a man 'thinks in his heart, so is he.' 'Out of the abundance of the heart his mouth speaks.' In other words, what is in us is going to come out of us. And 'above all else, guard your heart.' Do you hear that, Zach? Out of everything we do, protecting our hearts is the most important thing.We've got to guard them especially from anything that could come in and set up a lie about our God. Anything. I mean, even doing my work - and I'm a pastor - could convince me that God needs me in some way. That would be the perfect way for the enemy to set me up to wear myself out and shut myself down. And it would all start with a lie. The devil will try to convince us of anything - he's the father of lies, remember. And that is why we have to guard our hearts so carefully.”
