When I read Paul's post about making God a liar, I was reminded that this is exactly what happens during the tribulation. People will take the mark of the beast because they do not believe God's word that says it will doom them forever. Mankind has always been so zealous to try to make a liar out of God. This is one of the reasons they keep trying to land on other planets. They are hoping to find life outside of this earth  - so they can believe in evolution. ANYTHING, but believe God! Yet His word says that they are without excuse! They refuse the truth, so He sends them a great delusion so that they will believe a LIE.
