Sin begins in the mind. Sin will become more than a thought if you allow it.

The sinful mind will start with just one thought. The more you conceive, the more you give birth and what you think of continuously, you will eventually act on.

Get the snake eggs out of your head and think on whatsoever things are true, honest, just, pure, lovely, of good report, virtuous and praise-worthy! Philippians 4.8
