Obviously, in today's world, many deny the truth that Jesus is the Christ - they are antichrists. However, and thankfully, the Bible says that is temporary and one day everyone will know the truth that Jesus is both Christ and Lord.
“…every tongue will confess that Jesus Christ is Lord, to the glory of God the Father.” (Philippians 2:9-11)
"...no one can say, “Jesus is Lord,” except by the Holy Spirit." (1 Corinthians 12:3)
"This is good and acceptable in the sight of God our Savior, who wills all people to be saved and to come to the knowledge of the truth. For there is one God, and one mediator also between God and mankind, the man Christ Jesus, who gave Himself as a ransom for all, the testimony given at the proper time." (1 Timothy 2:3-5)
What a great day that will be! Everyone saved and filled with the Holy Spirit and knowing the truth that Jesus Christ is Lord - bringing glory to God.
