Jesus is concerned that we not have a critical spirit toward others, especially about their motives as to why they did something. We can't assume to know another person's heart; only God can. When we are unfairly critical, overly harsh, or unduly judgmental, we need to remember that God will use that same standard on us. I don't know about you, but I need grace. So do those I love. I'm going to try very hard to be as gracious toward others as I'm trusting that God is going to be gracious with me.
