The person does not know the christian ways..
Finally, brethren, whatever is true, whatever is honorable, whatever, is right, whatever is pure, whatever is lovely, whatever is of good repute, if there is any excellence and if anything worthy of praise, let your mind dwell on these things. [Philippians 4:8] .
That is what spells and prayers do..
Judge not, and ye shall not be judged: condemn not, and ye shall not be condemned, forgive, and ye shall be forgiven. [Luke 6:37]
This is what people contradict each other on.. if I was you.. I will direct them to the bible.. to question their own faith.. and leave yours alone..
