A familiar, is a wiccan spirit guide.
It only offers "wisdom" and strength to the "owner"
It does not do psychic abilities. The psychic abilities are within you, but you are not intended to use them for yourself. God has given gifts to mankind for a reason. I do not know which reason, but I know it is not ours to use if God doesn't give them to us.
I think the gift of looking into peoples hearts or feeling kinship with them, is linked to telepathy/empathy, but it is Gods to give to us.
We Christians do not need to spend hours and hours to practise these gifts. God gives them to us to use them to spread his kingdom. We need no instructions, we need no practise. We just get it and use is naturally.
God gives many gifts, and these gifts are worth more than anyone non christian can imagine.
It is so glorious and wonderfull to use your gift to spread the word of God and to see people being touched by it. To see a smile on their face as if something good has touched them(well God is good ).
