Therefore put on the full armor of God, so that when the day of evil comes, you may be able to stand your ground, and after you have done everything, to stand. (Ephesians 6:13)
Several passages of the New Testament speak of a coming day of evil, of temptation, of persecution, of unparalleled hardship:
For then there will be great distress, unequaled from the beginning of the world until now—and never to be equaled again. (Matthew 24:21)
Since you have kept my command to endure patiently, I will also keep you from the hour of trial that is going to come on the whole world to test the inhabitants of the earth. (Revelation 3:10)
You will be betrayed even by parents, brothers and sisters, relatives and friends, and they will put some of you to death. Everyone will hate you because of me. (Luke 21:16,17)
Paul advises us to put on the full armor of God so we might stand in the day of evil. The problem with the "rapture teaching" is that it informs us there will be no day of evil for anyone who "accepts Christ." Therefore there is no need to prepare ourselves.
Thus the American Christians of our day live careless lives. They may be able to see the unprecedented rebellions against authority of our day, as the nations of the East strive for democratic government. They may notice the diminishing of the United States as a world power. They may understand that the New Testament speaks of the great trouble to come.
But their attitude is: "There is no need for me to worry about the future. I will not be here. I will be caught up to Heaven in a "rapture" while the Jewish Christians preach the Gospel of the Kingdom during the troubled times of the Antichrist government.
Such unscriptural foolishness! But the attitude of "we won't be here," plus the unscriptural "lawless grace" teaching, have resulted in a woeful spiritual weakness of numerous American Christians. Our government reflects this lack of character in its confusion over moral issues.
