Matthew 16:7 They discussed this among themselves and said, ‘It is because we didn’t bring any bread.’
When Jesus warned His disciples about the leaven or yeast, He was talking figuratively rather than explicitly. The disciples started thinking about the physical and assumed He was talking about bread because they forgot to buy any!
How many times do we not listen to others properly and get the wrong end of the story?
God wants us to listen to Him carefully and understand what it is He requires from our lives, not just to listen to the words and do something!
