The World's leaders do not understand Ephesians 6, therefore the world is headed for Revelation 16

Ephesians 6:
¹⁰ A final word: Be strong in the Lord and in his mighty power. ¹¹ Put on all of God’s armor so that you will be able to stand firm against all strategies of the devil. ¹² For we are not fighting against flesh-and-blood enemies, but against evil rulers and authorities of the unseen world, against mighty powers in this dark world, and against evil spirits in the heavenly places.

Revelation 16:
¹³ And I saw three evil spirits that looked like frogs leap from the mouths of the dragon, the [LBL, Daniel 7, Rev 13:2] beast, and the false prophet [Mohammad]. ¹⁴ They are demonic spirits who work miracles and go out to all the rulers of the world to gather them for battle against the Lord on that great judgment day of God the Almighty.

¹⁵ “Look, I will come as unexpectedly as a thief! Blessed are all who are watching for me, who keep their clothing ready so they will not have to walk around naked and ashamed.” [note the context of Christ's second (not third) coming here in verse 15: it's around Judgment Day]

¹⁶ And the demonic spirits gathered all the rulers and their armies to a place with the Hebrew name Armageddon.

More on the second coming of Jesus Christ - when does he come back? On the "last day" at the "last trumpet".

John 6:
³⁵Then Jesus declared, "I am the bread of life. He who comes to me will never go hungry, and he who believes in me will never be thirsty. ³⁶But as I told you, you have seen me and still you do not believe. ³⁷All that the Father gives me will come to me, and whoever comes to me I will never drive away. ³⁸For I have come down from heaven not to do my will but to do the will of him who sent me. ³⁹And this is the will of him who sent me, that I shall lose none of all that he has given me, but raise them up at the last day. ⁴⁰For my Father's will is that everyone who looks to the Son and believes in him shall have eternal life, and I will raise him up at the last day.

⁴¹ Then the people began to murmur in disagreement because he had said, “I am the bread that came down from heaven.” ⁴² They said, “Isn’t this Jesus, the son of Joseph? We know his father and mother. How can he say, ‘I came down from heaven’?”

⁴³ But Jesus replied, “Stop complaining about what I said. ⁴⁴ For no one can come to me unless the Father who sent me draws them to me, and at the last day I will raise them up. ⁴⁵ As it is written in the Scriptures, ‘They will all be taught by God.’ Everyone who listens to the Father and learns from him comes to me. ⁴⁶ (Not that anyone has ever seen the Father; only I, who was sent from God, have seen him.)

⁴⁷ “I tell you the truth, anyone who believes has eternal life. ⁴⁸ Yes, I am the bread of life! ⁴⁹ Your ancestors ate manna in the wilderness, but they all died. ⁵⁰ Anyone who eats the bread from heaven, however, will never die. ⁵¹ I am the living bread that came down from heaven. Anyone who eats this bread will live forever; and this bread, which I will offer so the world may live, is my flesh.”

⁵² Then the people began arguing with each other about what he meant. “How can this man give us his flesh to eat?” they asked.

⁵³ So Jesus said again, “I tell you the truth, unless you eat the flesh of the Son of Man and drink his blood, you cannot have eternal life within you. ⁵⁴ But anyone who eats my flesh and drinks my blood has eternal life, and I will raise that person at the last day."

1 Corinthians 15:
⁵⁰I declare to you, brothers, that flesh and blood cannot inherit the kingdom of God, nor does the perishable inherit the imperishable. ⁵¹Listen, I tell you a mystery: We will not all sleep, but we will all be changed— ⁵²in a flash, in the twinkling of an eye, at the last trumpet [what's the last trumpet mentioned in the Bible?]. For the trumpet will sound, the dead will be raised imperishable, and we will be changed.
