That question has been asked by more than one skeptic, and I have to admit that the idea does sound a little hard to believe. The question is referring to the verse in I Corinthians 15:52 which says, “In a moment, in the twinkling of an eye, at the last trump: for the trumpet shall sound, and the dead shall be raised incorruptible, and we shall be changed.”
This verse is referring to an event known as the rapture, which is a time in the future when Jesus will descend into the clouds and call His children to be with Him. At this time every living Christian will go to heaven, and the bodies of the believers that have died will be resurrected and glorified. The Christians who are alive will also receive a glorified body that will be theirs for all eternity.
So to go back to the skeptic’s question, do I really believe that God can change all these people in the twinkling of an eye? Of course I do.
I know this because He already changed me once. The very second I chose to put my faith and trust in Jesus I became a new creation; the old has passed away. There are some parts that change over time, and this is a process called sanctification, but there was a part of me that changed instantly.
Ray Comfort compares this change to a man that promises to give you $100 million when he returns, and just so that you will believe him, he gives you a million dollars up front. Is the $100 million hard to believe? Yes, but it is easier to believe that he will keep his promise when he gives you a million dollars.
God has promised to do something incredible by changing us in the twinkling of an eye ($100 million), but He has already given us a glimpse of the change He can produce (1 million dollars). But not everyone will receive this promise.
Do you want to be changed in the twinkling of an eye? If you want to have that glorified body in heaven one day you have to first be changed by God on earth. Put your faith in Jesus and let His Holy Spirit change you.
