Our God is a Jealous God

I've had a few conversations with my mother on the topic of prophets and dreamers. Because my mother is a dreamer of dreams that come true, she's often wondered how her gift relates to our faith in Yahweh, in comparison to those outside of the faith, who practise fortune telling and the likes. As well, her experience with the occult prior to coming to know Yeshua (Jesus), has caused her to shy away from using this gift that the Father has given her.
In our conversations we've come to the conclusion that when God gives out gifts he gives them to everyone, so if a person is not following God they still have their gifts, only they are using them for the wrong side of the team, so to speak.

I came across an interesting passage in Deuteronomy 13:that has given me another possibility with regard to this topic. This is what it says " If a prophet or a dreamer of dreams arises among you and gives you a sign or a wonder, and the sign or wonder that he tells you comes to pass, and if he says, 'Let us go after other gods,' which you have not known, 'and let us serve them,' you shall not listen to the words of that prophet or that dreamer of dreams. For the Lord your God is testing you, to know whether you love the Lord your God with all your heart and with all your soul. You shall walk after the Lord your God and fear him and keep his commandments and obey his voice, and you shall serve him and hold fast to him."

The rest of the chapter continues on to warn those who love God to purge out the evil, not letting anyone lead you away from His commandments. What makes this interesting is that one of the ways God tells us to judge whether a prophet's "word" is from Him is by what comes true of his prophecy. This is explained in Deuteronomy 18: 9-22. So our loving Father will actually allow a accurate prophets/dreamers into our lives, with the idea of testing our hearts. He wants to see if we will be won over by their words, setting aside what He's told us. Will they lead us away to worship idols and other gods?
The two "witnesses" for us to judge whether or not some prophet is reliable are: 1. What they say must come true?
2. They must not entice us to go after other gods.

Basing our judgement on this criteria we can use the Word of God to assess whether someone is legitimately speaking on Yahweh's behalf or not.
Thanks Father for your Word.
