Atheists should be most upset and protest the secular promotion of Halloween for all it's superstition and false religion. The great irony is that it is precisely the "atheist" who promote the most outrageous cults! Even public schools propagandize for this religious feast. No Baby Jesus for Christmas but witches, ghosts, jack-o-lanterns, etc. for Halloween.
The problem with atheists is not that they don't believe but that they believe too much! Anything and everything but Christ!
Just one more proof that Jesus Christ is the Truth and there is no other: The Way, The Truth and The Life. Everything else is confusion, darkness and death! "Whoever rejects the Son rejects the Father Who sent Him!"
Luke 12
8And I say to you, Whosoever shall confess me before men, him shall the Son of man also confess before the angels of God. 9But he that shall deny me before men, shall be denied before the angels of God. 10And whosoever speaketh a word against the Son of man, it shall be forgiven him: but to him that shall blaspheme against the Holy Ghost, it shall not be forgiven.
22Who is a liar, but he who denieth that Jesus is the Christ? This is Antichrist, who denieth the Father, and the Son. 23Whosoever denieth the Son, the same hath not the Father. He that confesseth the Son, hath the Father also.
N.B. Never believe something because it is convenient or because it makes you feel good. Believe it because its true! The primacy of truth is the primacy of God! Therefore, the honest atheist is already a believer! He believes in the truth and thus tirelessly searches for it, which is not an it but an "I": relationship: the "I Am!" "Yahweh."
Father, Son and Holy Spirit: that is the truth behind every honest quest.
Happy Eve of All Saints Day. God calls you to be a Saint too!
