Read the series so far.
Christians are not immune from thinking independently of God. We do it when we think we can circumvent clear passages which we would rather say something other than what they say.
We can see this in two episodes in the life of our Lord.
In the first, Jesus warns the disciples to “Take heed and beware of the leaven of the Pharisees and Sadducees” (Matt. 16:6). The narrative then says the disciples “reasoned among themselves, saying, ‘It is because we have taken no bread.’” This brought forth a rebuke from Jesus:
O you of little faith, why do you reason among yourselves … do you not understand … How is it you do not understand that I did not speak to you concerning bread? – but to beware of the leaven of the Pharisees and Sadducees. (Matt. 16:8-11)
Then the narrative tells us that “they understood that He did not tell them to beware of the leaven of bread, but of the doctrine of the Pharisees and Sadducees.”
