Testing, Part 2

Deuteronomy 13:3
you must not listen to the words of that prophet or dreamer. The LORD your God is testing you to find out whether you love him with all your heart and with all your soul.

That prophet or dreamer is one who announces a miraculous sign or wonder--and it comes true! Impressive! Who wouldn't listen?
But then the prophet follows up with a call to worship another god. It is a test. Don't listen! The words can be persuasive, especially if they are backed up with supernatural power.
What matters is the god in question. This kind of cool because the believer is expected to use her head, not giving in to mere experience. We are expected to know the God of the Bible and to recognize when it isn't Him.
I can do that if I love Him with all my heart, if my heart isn't fragmented, with large chunks obsessed with myself, smaller bits enthralled with money, emotion, vanity. Those idolatrous obsessions leave me vulnerable to other gods.
"Blessed are the pure of heart, for they shall see God."
