My pastor for YEARS has used the celebration of Halloween to reach children in the area with the gospel that might not have been exposed to because their parents don't take them to church. Anyone so legalistic as not to see the wisdom in that is the one with insecure faith.
And, BTW, if you have sincerely accepted Jesus Christ as your Savior, you have secured a spot in heaven. Salvation is a free gift that doesn't have to be earned.
It’s not a question of being able to evade the love of Calvary. It’s a question of best serving the Lord. There’s a point in a Christian walk when one begins to be surprised by seeing supernatural blessings. At that point, the Lord will begin to show more jealousy too, as we don’t have an excuse for doubt.
There could be good things in “trunk-or-treats.” I am not cursing them. The question is how to progress from good to better. One possibility could be a “Victory Night.”
I wrote in my reply to you and others that I believe that Christians can be led by the Lord to use Halloween in a different way, essentially turning it into a different, competing holiday. But I certainly believe that Christians can be led to by the Lord oppose those similar celebrations because of the Satanism at the bottom of the original, and also to speak out against it. What is wrong is to just accept and defend Halloween as it is, dismissing that it’s one of Satan’s many destructive tools.
