No, not "all flesh" will worship Yahweh Yireh or Yeshua Ha' Mashiach. That being said, EVERY knee shall bow before Him. John 1 Amplified Bible (AMP) 14And the Word (Christ) became flesh (human, incarnate) and tabernacled (fixed His tent of flesh, lived awhile) among us; and we actually saw His glory (His honor, His majesty), such glory as an only begotten son receives from his father, full of grace (favor, loving-kindness) and truth.
15John testified about Him and cried out, This was He of Whom I said, He Who comes after me has priority over me, for He was before me. He takes rank above me, for He existed before I did. He has advanced before me, because He is my Chief.
16For out of His fullness (abundance) we have all received all had a share and we were all supplied with one grace after another and spiritual blessing upon spiritual blessing and even favor upon favor and gift heaped upon gift. Romans 14 Amplified Bible (AMP) 11For it is written, As I live, says the Lord, every knee shall bow to Me, and every tongue shall confess to God acknowledge Him to His honor and to His praise. Philippians 2 Amplified Bible (AMP) 10That in (at) the name of Jesus every knee ashould (must) bow, in heaven and on earth and under the earth 11And every tongue bfrankly and openly confess and acknowledge that Jesus Christ is Lord, to the glory of God the Father.
Isaiah 45 Amplified Bible (AMP) 23I have sworn by Myself, the word is gone out of My mouth in righteousness and shall not return, that unto Me every knee shall bow, every tongue shall swear allegiance.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
