There are some suggestions about how this superstition originated but however it began, the question should be asked, how should Christians feel about Friday the 13th (and other superstitions)?

All superstitions are unbiblical. Friday the 13th, walking under a ladder, a black cat crossing your path, spilling salt, etc. are not something for Christians to fear.  The dictionary defines superstition as “a widely held but unjustified belief in supernatural causation leading to certain consequences of an action or event, or a practice based on such a belief.”  NOTE that it says, “unjustified belief in supernatural causation.”  

As Christians we live by a firm and justified belief in the proven and trustworthy Word of God. 

Prov 30:5  Every word of God is pure: He is a shield unto them that put their trust in Him.

1 Th 2:13  For this reason we also thank God without ceasing, because when you received the word of God which you heard from us, you welcomed it not as the word of men, but as it is in truth, the word of God, which also effectively works in you who believe.

Every day of life is a gift from God.  Have a blessed Friday the 13th!
