During the tribulation, what will make-up the one-world church?
All people who have not given their lives to Jesus Christ will be a part of the one-world church. They will be deceived into worshipping the Antichrist until it is too late to turn back. These people will think that they are worshipping the Messiah and will do so gladly and blindly because they did not know the true Messiah. Unfortunately, many of these people will have called themselves Christians.
Do you know the true Messiah as your personal Savior and Lord? Do you know Him intimately? Would you recognize a slick impostor? If you have any doubt, then your salvation is in question. Ask the Lord to reveal Himself to you and to draw you unto Him. Ask Him to forgive your sins, especially the pride that has kept you from surrendering to Him until now.
