"Every knee shall bow, and every tongue shall confess that Jesus Christ is Lord..." (Isaiah 45; Philippians 2:11-12)
"...no one can say, “Jesus is Lord,” except by the Holy Spirit." (1 Corinthians 12:3)
Therefore, everyone will one day be filled and sealed with Holy Spirit
"In Him, you also, after listening to the message of truth, the gospel of your salvation—having also believed, you were sealed in Him with the Holy Spirit of the promise." (Ephesians 1:13}
