Should a Christian celebrate Halloween or not? I get questions like this all the time. Do I listen to this music? Participate in this group? Get the vaccine? Read this book? etc... My answer is always the same. Does whatever you are deciding about draw you into a deeper relationship with God and a greater dependence on Him or does it pull you toward self, world and people? It is a choice you must make.
Do people see the Bible in action when they pass by your home or is it the world in motion? Are you seeking man's approval or God's?
1 Samuel 16:7 (ESV) says, "But the Lord said to Samuel, “Do not look on his appearance or on the height of his stature, because I have rejected him. For the Lord sees not as man sees: man looks on the outward appearance, but the Lord looks on the heart."
