So you're actually establishing the authority of Jesus Christ through the law of Moses?T How pitiful.
Straw man.
Jesus received commandment directly from the Father.
Joh 5:27 And hath given him authority to execute judgment also, because he is the Son of man.
The Law of Moses was given by the Father, so there is no disagreement.
Seriously? God has the same requirements that He has given to His subjects?
God way is the way that He expresses His nature through His action and God gave His law to teach us how to walk in His way.
Straw man.
David did not obey the law.
Luk 6:4 How he went into the house of God, and did take and eat the shewbread, and gave also to them that were with him; which it is not lawful to eat but for the priests alone?
notice the statement "not lawful".... So go ahead and explain it away.
Some of God's laws appear to conflict with each other, such as when God commanded priests to rest on the Sabbath and commanded priests to make offering on the Sabbath (Numbers 28:9-10), however, it was not the case that they were forced to sin by breaking one of the two commandments no matter what they chose to do, but that the lesser command was never intended to be understood as preventing the greater commandment from being obeyed. This is why Jesus said in Matthew 12:5-7 that priests who did their duties on the Sabbath were held innocent, why David and his men were held innocent, and why he defended his disciples as being innocent. This is also why it we are permitted to get a child or an ox out of a ditch on the Sabbath or why babies should still be circumcised on the 8th day if it happens to fall on the Sabbath and so forth.
Are we allowed to tell a lie in order to save someone's life? These sorts of dilemmas are why there is debate about which commandments are greater or which is the greatest. Some might consider laws that have the harshest penalty for breaking to be the greatest, or laws that the Israelites were most frequently criticized for breaking to be the greatest, or the law that God specifically said to remember, and so forth.
Some of the Pharisees had reasoned that it is unlawful to work on the Sabbath and that healing is work, therefore it is unlawful to heal on the Sabbath. However, we are also commanded to love our neighbor as ourselves and we would not be doing that if we refused to heal someone who needed our help. No command was intended to be understood a preventing the greatest two commandments from being obeyed, which is why Jesus was not breaking the Sabbath by healing on it.
While David and his men did what was unlawful by eating of the showbread, they were not sinning because the preservation of life is greater, but that does not mean that David did not obey God's law.
