I draw an illustration from a commercial I saw. God is standing in a room full of little girls, and He announces to the whole room, "I'm giving a big party, and whosoever will may come!" His only stipulation is that each one get an embossed personalized invitation, which He begings to hand out individually. There are twenty girls in the room and 7 get invitations but then there are no more invitations for any of the rest. "Too bad girls," an attendant says, " but you can't come, because you did not get an invitation." The girls say, "But He said whosoever will may come!" The attendant says, Yes, but He wasn't talking about you.
Some Christians allow themselves to think God is like this for some reason. That is not true, however, because God is not willing that any should perish, but wills for ALL to come unto the knowledge of the truth. Trying to redefine the word "all" to suit wrong doctrine will not be allowed by God.
