“…every tongue will confess that Jesus Christ is Lord, to the glory of God the Father.” (Philippians 2:11)
Everyone belongs to the LORD and all will confess that Jesus Christ is LORD, or the Bible is just another book. Further, the LORD Jesus Christ said this...
“And this is the Father's will which hath sent Me, that of ALL which He hath given Me I should lose nothing, but should raise it up again at the last day.” (John 6:39)
The Apostle Paul said this...
“Now I make known to you, brethren, the gospel which I preached to you… that Christ died for our sins according to the Scriptures” (1 Corinthians 15:1-4)
“…while we were yet sinners, Christ died for us. Much more then, having now been justified by His blood, we shall be saved from the wrath of God…” (Romans 5:8-9)
"Trustworthy is the saying, and worthy of full acceptance, that Christ Jesus came into the world to save sinners" (1 Timothy 1:15)
“Now I make known to you, brethren, the gospel which I preached to you… that Christ died for our sins according to the Scriptures” (1 Corinthians 15:1-4)
“…while we were yet sinners, Christ died for us. Much more then, having now been justified by His blood, we shall be saved from the wrath of God…” (Romans 5:8-9)
"Trustworthy is the saying, and worthy of full acceptance, that Christ Jesus came into the world to save sinners" (1 Timothy 1:15)
"It is a trustworthy statement deserving full acceptance. For it is for this we labor and strive, because we have fixed our hope on the living God, who is the Savior of all mankind, especially of believers. Prescribe and teach these things." (1 Timothy 4:9-11)
Mankind is the Lord's and therefore all will be saved. This is the Good News that the Bible teaches. If "all" are not saved, the Bible is not the word of God.
