The none believers even if they never except Christ as there saviour in this life they will except him when they are resurrected for their 2nd and final death after the 1000 year reign. Philippians 2:10-11New King James Version (NKJV)
10 that at the name of Jesus every knee should bow, of those in heaven, and of those on earth, and of those under the earth, 11 and that every tongue should confess that Jesus Christ is Lord, to the glory of God the Father. Romans 14:11New King James Version (NKJV)
11 For it is written:
“As I live, says the Lord,
Every knee shall bow to Me,
And every tongue shall confess to God.”[a]
