There are many reasons why Halloween is of the devil and I pray that you will stop participating in it if you have not already.
3 John 1:3,4 (KJV)
3 For I rejoiced greatly, when the brethren came and testified of the truth that is in thee, even as thou walkest in the truth.
4 I have no greater joy than to hear that my children walk in truth.
When people follow Jesus, they also love what He loves and hates what He hates. We don’t hate people but sin.
3 John 1:11 (KJV)
11 Beloved, follow not that which is evil, but that which is good. He that doeth good is of God: but he that doeth evil hath not seen God.
How can people say they have God in their lives while still participating in Halloween? This goes against His will for us.
Counsel with the Lord in prayer. Share His gospel with boldness. When Jesus is our shield there is no fear.
