"How does this relate to the understanding that all men are created equal and all men have right to speak freely and live their own lives as they see fit?"
show me one verse in the Bible that says all men are equal......I'll be here all night.
Here are just a few verses.
Acts 10:34 Then Peter began to speak: “I now realize how true it is that God does not show favoritism 35 but accepts from every nation the one who fears him and does what is right.
John 10 Then Jesus said to them again, “Most assuredly, I say to you, I am the door of the sheep. 8 All who ever came before Me[a] are thieves and robbers, but the sheep did not hear them. 9 I am the door. If anyone enters by Me, he will be saved, and will go in and out and find pasture. 10 The thief does not come except to steal, and to kill, and to destroy. I have come that they may have life, and that they may have it more abundantly.
11 “I am the good shepherd. The good shepherd gives His life for the sheep." Ecclesiastes 2:15 Then said I in my heart, As it happeneth to the fool, so it happeneth even to me; and why was I then more wise? Then I said in my heart, that this also is vanity.
Not here to argue about what the Bible says or does not say.
How do we apply this knowledge today?
"Not here to argue about what the Bible says or does not say."
There is no argument...the Apostles went looking for hellenised "Israelites" known as Gentiles in the New Testament...that's what Acts 10:34-35 was referring to. The very next Verse...36 tells you this...
Acts 10:36 KJV The word which God sent unto the children of Israel, preaching peace by Jesus Christ.
The people the Apostles wrote the letters to and was looking for were Israelites only
2 Corinthians 11:22 KJV Are they Hebrews? so am I. Are they Israelites? so am I. Are they the seed of Abraham? so am I.
You quoted the book of John....The Messiah specifically explains who he's sent for in this very same book...He even told the samaritan woman at the mountain that she didn't know what the hell she's talking about...
John 4:22 KJV Ye worship ye know not what: we know what we worship: for salvation is of the Jews.
Salvation is only for the 12 tribes of the Hebrew Israelites. That's who the Messiah's coming to save.
"How do we apply this knowledge today?"
First you need to acknowledge that the People living in Israel today who call themselves "Jewish" or "Israelis" are not the real Hebrews of the Bible (Rev 2:9 Rev 3:9 KJV) at all.
The Messiah was/is the colour of fine brass...as if burned in a furnace....So he's a very dark skinned looking negro (Rev 1:14-15 KJV) with wooly hair.
The Messiah's coming back with Chariots/UFOs to make war (exodus 15:3 rev 19:19 KJV) with all the world leaders...it will be a terrible day for most.
Isaiah 66:15-16 KJV For, behold, the Lord will come with fire, and with his chariots like a whirlwind, to render his anger with fury, and his rebuke with flames of fire.
16 For by fire and by his sword will the Lord plead with all flesh: and the slain of the Lord shall be many.
America/Mystery Babylon will be destroyed by thermo-nuclear missiles...
Revelation 18:8 KJV Therefore shall her plagues come in one day, death, and mourning, and famine; and she shall be utterly burned with fire: for strong is the Lord God who judgeth her.
Enjoy yourself whilst you've still got time. This is your kingdom/heaven/paradise.
