I was studying Matthew 19 and noticed vss. 16-18. What follows is my commentary on them:
Thus begins Jesus' teaching on the essential works required for eternal life. The seeker addressed Jesus as "Good Teacher." Then he asked the simplest of questions, "What good to perform in order to possess life everlasting?"The seeker recognized and confessed to Jesus that he considered the Teacher good; not necessarily as a quality teacher, but as a good person who was a teacher.Jesus inquired about the use of the word "good" as applied to to himself, and explained that only God is good. Note, Jesus did not contradict the seeker or rebuke him for using a word to describe him that should only be used to describe God.Then Jesus answered the question in his own terms, "If you want to enter into the life, keep the commandments." Jesus answered the seeker's question about life everlasting by referring to the life as the only life that mattered.In answer to the seeker's question, "But which (commandments)?" Jesus specified not murdering, committing adultery, stealing, witnessing falsely, (and in vs. 19) honoring parents and loving neighbors as self; all commandments regarding behavior toward other people.Perhaps Jesus recognized that the seeker lived carefully with regard to honoring God through the ceremonial laws, but had issues with treating others according to the spirit of the law. In any case, Jesus did not specify religious observance as being required to gain life everlasting.
In the New Testament's context, this is a good indication that observing the seventh-day Sabbath was not a high priority to Jesus. While Jesus didn't specifically exempt us from observing the Sabbath, by not including it as a requirement to gain eternal life, along with all the other ceremonial laws, he inferred that he personally fulfilled them all.
