How can demons tempt us to sin?
When you make an idol or worship idols it has happened already. 1 cor 10:
19 What say I then? that the idol is any thing, or that which is offered in sacrifice to idols is any thing?
20 But I say, that the things which the Gentiles sacrifice, they sacrifice to devils, and not to God: and I would not that ye should have fellowship with devils.
21 Ye cannot drink the cup of the Lord, and the cup of devils: ye cannot be partakers of the Lord's table, and of the table of devils.
