The unsaved mind cannot understand Biblical precepts because they are derived from the Holy Spirit which lost people, including religious people, do not have.
Mt 22:41-46 While the Pharisees were gathered together, Jesus asked them, Saying, What think ye of Christ? whose son is he? They say unto him, The Son of David. He saith unto them, How then doth David in spirit call him Lord, saying, The Lord said unto my Lord, Sit thou on my right hand, till I make thine enemies thy footstool? If David then call him Lord, how is he his son? And no man was able to answer him a word, neither durst any man from that day forth ask him any more questions.
LESSON - Jesus had been approached by the religious leaders with questions on many occasions in order to ensnare him. This passage shows an instance where Jesus turned the tables. He inquires of the religious leaders their beliefs regarding the Messiah. When they replied that he would be a son of David, Jesus refers to Psalms when he asked “How then can David called him Lord?” He would have to pre-exist David, yet still be physically born from David’s lineage. Jesus had literally just taught them about the necessity of the virgin birth. They could not perceive it’s meaning because religion couldn’t understand what it takes a relationship to discern. We should not expect lost people to understand Biblical concepts because they lack the Holy Spirit’s presence in their lives. This explains their belief system as well as their lifestyle. Religion seeks to change them on the outside. Only a relationship with Jesus can change them from within. Remember this when we have a tendency to be judgmental toward others. Before people can change, they must first have the desire for change which can only come through a relationship with Jesus.
