The Fifth Commandment, "20:12 Honour thy father and thy mother: that thy days may be long upon the land which the LORD thy God giveth thee" (Exodus 20:12 KJV) is one of the pillars of a civilized society. It's something that animals don't do. But the Commandment of honoring our parents also has an ultimate meaning that directly involves salvation. The Church of God (i.e. which means people, the "called out ones" - see What Is The Church?), which is referred to as a woman, is our mother (see Why Did Jesus Have Brothers and Sisters?), while God is our Father (see the Fact Finder question below to understand how we are conceived children of God).
While we are to honour our honorable physical fathers, we are also, moreover, to honour God, our ultimate Father because He too is "raising" us.
"12:5 And ye have forgotten the exhortation which speaketh unto you as unto children, My son, despise not thou the chastening of the Lord, nor faint when thou art rebuked of him: 12:6 For whom the Lord loveth he chasteneth, and scourgeth every son whom he receiveth.
"Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven"
We honour our Father in heaven not with vain words, but with actual obedience to His Word.
"5:14 Ye are the light of the world. A city that is set on an hill cannot be hid. 5:15 Neither do men light a candle, and put it under a bushel, but on a candlestick; and it giveth light unto all that are in the house. 5:16 Let your light so shine before men, that they may see your good works, and glorify your Father which is in heaven." (Matthew 5:14-16 KJV)
God is our Judge. It is not our business to sit in judgment of those who may not yet have received their awareness, or who have rejected it. God will decide who His children are.
"5:44 But I say unto you, Love your enemies, bless them that curse you, do good to them that hate you, and pray for them which despitefully use you, and persecute you; 5:45 That ye may be the children of your Father which is in heaven: for he maketh his sun to rise on the evil and on the good, and sendeth rain on the just and on the unjust." (Matthew 5:44-45 KJV)
The very famous "LORD Prayer" was not meant to be a prayer in itself. Consider the full context of Christ's teachings, and the context in which the "LORD Prayer" was instructed. It becomes plain that it was an outline for what to pray for - as well as a verbal commitment to being good children of God by obeying Him.
"6:1 Take heed that ye do not your alms before men, to be seen of them: otherwise ye have no reward of your Father which is in heaven.
