But your leaving out the first and foremost command before love your neighbors and that is:
Mar 12:29 And Jesus answered him, The first of all the commandments is, Hear, O Israel; The Lord our God is one Lord:
Mar 12:30 And thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind, and with all thy strength: this is the first commandment.
Mar 12:31 And the second is like, namely this, Thou shalt love thy neighbor as thyself. There is none other commandment greater than these.
Before loving our neighbors fulfill anything, we must Love God first.
How do we show we Love Him, not by simply saying it.
Jn 14:15 - if ye love me keep my commandments
The covenant changed not God. He is the same, none of His attributes have changed, but the covenant did.
Heb_8:8 For finding fault with them, he saith, Behold, the days come, saith the Lord, when I will make a new covenant with the house of Israel and with the house of Judah:
Heb 8:9 Not according to the covenant that I made with their fathers in the day when I took them by the hand to lead them out of the land of Egypt; because they continued not in my covenant, and I regarded them not, saith the Lord. Heb_8:13 In that he saith, A new covenant, he hath made the first old. Now that which decayeth and waxeth old is ready to vanish away.
Heb_12:24 And to Jesus the mediator of the new covenant, and to the blood of sprinkling, that speaketh better things than that of Abel.
No my wife is my wife, physically, literally, however you want to look at it.
God has given woman for man, and He instituted marriage, and He has bound me together with my wife:
Mat 19:4 And he answered and said unto them, Have ye not read, that he which made them at the beginning made them male and female,
Mat 19:5 And said, For this cause shall a man leave father and mother, and shall cleave to his wife: and they twain shall be one flesh?
Mat 19:6 Wherefore they are no more twain, but one flesh. What therefore God hath joined together, let not man put asunder.
