We are bombarded by advertising every single day. Restaurants serve us pictures of food that bears little resemblance to what actually shows up in front of paying customers. Amazing deals are advertised only to be undermined by the ‘small print’. With all the sensational promises we hear, it is hard for us to know how to sort through which ones to believe, and which ones to ignore. Christianity isn’t immune to this dynamic either. Teachers proclaim to have the pathway to God or the inside track on how to make life work. But they often disagree with one another. How are we to know which ones to believe and which ones to ignore? Jesus has a stunningly simple solution. It is one that helps us sort through the teachers around us; but it also helps us weed out our own souls!
