That's because there is God's way(narrow) and then there is the way of the world (the broad road that leads to destruction.)
ET people are assuming that death settles everything. That is not biblical.
In this life, choosing the way of the world will cause you misery, heartache, strife, and ultimately the lifestyle will destroy you.
Choosing the way of the Lord will cause you love, joy, peace, patience, long-suffering, and contentment.
Our merciful Father could bring anyone He wants to to Christ at anytime. For his own reasons and purposes, he brings most people to Christ -after they die. Otherwise, the devil "wins" in the sense that hardly anyone (comparitively) comes to know Christ in this life. Since ET people believe your chance is over when you die, they must believe that the devil is stronger than God.
The Bible clearly states , "God WILLS all men to be saved." So, who can thwart God's will? Apparently ET'ers think mans or the devils will is stronger than God. - I know Saul/Paul didn't think so and neither do any UR people.
