New Testament Teaching concerning the Sabbath

Jesus plucked grain on the Sabbath, thus breaking the Sabbath traditions according to the Jews of His day (Matthew 12:1-8; Mark 2:23-28; Luke 6:1-10). Jesus healed on the Sabbath, again raising the ire of the Jews, who accused Him of being a Sabbath breaker (Luke 13:10-17; John 5:1-18). Jesus ate with a chief Pharisee on the Sabbath (Luke 14:1). Not once did Jesus indicate or tell anyone to observe a certain day for a Sabbath. If Jesus intended for us to keep the Sabbath in the New Testament, why did He not mention it along with the other requirements to the rich young ruler? (Matthew 19:16-22). Jesus taught that the law was fulfilled when we love God and our neighbor as ourselves, not when we observe the Sabbath (Matthew 22:34-40; Romans 13:8-10; Galatians 5:14; James 2:8).
