In Lev 18:16, we have what the Jews called the central commandment which is “Do not seek revenge or bear a grudge against anyone amongst your people, but love your neighbour as yourself. I am the Lord”. These were the commandments quoted by Jesus to the Pharisees. If they had read into Lev 18.16, they would have realised the hidden message Jesus was claiming, “I am the Lord”, the master of the house in Luke 16:1-9 was coming back.
The Pharisees who were gatekeepers of the law failed in the Great Commandment because God was not the Lord of their lives. In Luke 16:14, the pharisees derided Jesus because He told them that they could not serve two masters. In luke 16:19 to 31, Jesus told another story to taunt the Pharisees where they were now the rich man in the story because they only loved themselves and not their neighbour nor Jesus as Lord. Through their unbelief they had rejected Jesus even though Jesus had resurrected from the dead. One is not saved simply being from the lineage of Abraham or being a person of faith. They could not see Jesus because money was their master. Do you believe Jesus as your Messiah, your Lord and Saviour!
