The Bible often talks about our hearts as soil (parable of the sower). I want to talk about how to tend that soil that it produces spiritual fruit. We will be held accountable for every careless word (Matthew 12:36), but it is out of the overflow of the heart that the mouth speaks (Matthew 12:34), therefore we must learn to guard and tend our own heart. If our heart is pure, so will our mouth be (James 3:8-13). Don’t just protect from people hurting it, but protect from the world corrupting it, busyness, etc.
