Exodus 20:12 KJVS
“Honour thy father and thy mother: that thy days may be long upon the land which the Lord thy God giveth thee.”
That thy days be long upon the land which the Lord thy God giveth thee.
Ephesians 6:1-3 KJVS
“Children, obey your parents in the Lord: for this is right.  Honour thy father and mother; (which is the first commandment with promise;)  That it may be well with thee, and thou mayest live long on the earth.”
That thou mayst live long on the earth. Yes New Heavenly Jerusalem is coming here, when we move into the Third World Age, which is Eternity.
Revelation 21:1-2 KJVS
“And I saw a new heaven and a new earth: for the first heaven and the first earth were passed away; and there was no more sea.  And I John saw the holy city, new Jerusalem, coming down from God out of heaven, prepared as a bride adorned for her husband.”
Prepared as a Bride adorned for her Husband who is Jesus Christ, and if you seen Him you seen the Father (John Chapter 14:6-10, John Chapter 5:23)
This is the first Commandment with promise, a promise of an Eternal Inheritance through Jesus Christ.
Honor Thy Father.
1 Samuel 2:30 KJVS
“Wherefore the Lord God of Israel saith, I said indeed that thy house, and the house of thy father, should walk before me forever: but now the Lord saith, be it far from me; for them that honour me I will honour, and they that despise me shall be lightly esteemed.”
Proverbs 3:1-9 KJVS
“My son, forget not my law; but let thine heart keep my commandments:  For length of days, and long life, and peace, shall they add to thee.  Let not mercy and truth forsake thee: bind them about thy neck; write them upon the table of thine heart:  So shalt thou find favour and good understanding in the sight of God and man.  Trust in the Lord with all thine heart; and lean not unto thine own understanding.  In all thy ways acknowledge him, and he shall direct thy paths.  Be not wise in thine own eyes: fear the Lord, and depart from evil.  It shall be health to thy navel, and marrow to thy bones.  Honour the Lord with thy substance, and with the firstfruits of all thine increase:”
We forget not His Law, and we let our heart keep His Commandments which is His Words(substance). We do this by loving Him with all of our heart, by staying within His Word, and loving others by feeding them His Word.
We honor our Heavenly Father with substance He gives us, and first fruits of our increase (Matthew Chapter 13: 23).
Honor Thy Mother.
Galatians 4:26-31 KJVS
“But Jerusalem which is above is free, which is the mother of us all.  For it is written, Rejoice, thou barren that bearest not; break forth and cry, thou that travailest not: for the desolate hath many more children than she which hath an husband.  Now we, brethren, as Isaac was, are the children of promise.  But as then he that was born after the flesh persecuted him that was born after the Spirit, even so it is now.  Nevertheless what saith the scripture? Cast out the bondwoman and her son: for the son of the bondwoman shall not be heir with the son of the freewoman.  So then, brethren, we are not children of the bondwoman, but of the free.”
Free indeed, if you are a citizen of the Heavenly Jerusalem which is above.
You become a citizen of the Heavenly Jerusalem, which is your Mother, by believing upon the only begotten Son, Jesus Christ, and you maintain your citizenship by staying with the substance He gives you which is His Words.
We see Jesus address His Mother and His brethren in Luke Chapter 8.
Luke 8:19-21 KJVS
“Then came to him his mother and his brethren, and could not come at him for the press.  And it was told him by certain which said, Thy mother and thy brethren stand without, desiring to see thee.  And he answered and said unto them, My mother and my brethren are these which hear the word of God and do it.”
Which HEAR the Word of God, and DO IT.
Christ would say this after He spoke of the Parable of the Seed of the Sower.
The Seed is the Word of God, that you Sow, and the increase that you honor your Heavenly Father with, are those in which you are used to bring back home to their Mother, New Heavenly Jerusalem that will come down from God as it is written in Revelation Chapter 21 verse 2.
Heavenly Jerusalem consist of those who hear the Word of God and do it which are His (Hebrews Chapter 2 verses 9 through 12) Brethren (God’s Servant’s). They are all that are Heavenly Father has used throughout the ages and will continue to use throughout this final generation to bring many to the Captain of our Salvation, Jesus Christ, and into a city that is above, which is Eternal and Free.
Honoring Thy Father, and Thy Mother, is loving our Heavenly Father with all your heart, and loving those in whom you are used to bring Back Home and loving your fellow brethren that are being used to do the same.
I believe this is what lies within the two greatest Commandments.
Matthew 22:36-40 KJVS
“Master, which is the great commandment in the law?  Jesus said unto him, Thou shalt love the Lord thy God with all thy heart, and with all thy soul, and with all thy mind.  This is the first and great commandment.  And the second is like unto it, Thou shalt love thy neighbour as thyself.  On these two commandments hang all the law and the prophets.”
And for this our Lord is not ashamed to call us His brethren.
Honor Him, and the Body that you a part of.
