How do you know you have the Holy Spirit?

Something I have been thinking on recently, how do you know that God lives in you?
(Would love people to answer this one!)

Sometimes I feel like I have chosen God, but I wonder if I have been chosen by Him. Where is the evidence of Him in my life? How am I living differently to those who don't have the Holy Spirit within them?

There should be a dramatic difference right? This is GOD we are speaking about. In me!! Why can I not see more evidence of this?!?!

Hubby says he can see differences in me that only God can do. The changing of my heart in certain things. Increase of the Fruit of the Spirit as I grow closer to Him. Takes a while though... and sometimes I wonder if that it is just me trying really hard and following His Word, or by listening to sermons, it is God in the preacher who is guiding me - instead of the Holy Spirit within me.

I guess the loss in desire to sin would be evidence? I place pleasing God higher in priorities then my own comfort or desires. Scripture says our flesh and God's Spirit are at war - so there should be obvious evidence there?

(Galatians 5) So I say, let the Holy Spirit guide your lives. Then you won’t be doing what your sinful nature craves. The sinful nature wants to do evil, which is just the opposite of what the Spirit wants. And the Spirit gives us desires that are the opposite of what the sinful nature desires. These two forces are constantly fighting each other, so you are not free to carry out your good intentions.

I really just want to make sure that I am His child, and not just misleading myself and working on these things in my own strength and fooling myself. There are so many 'good' people out there, who don't have the Holy Spirit, and I wonder if we are just doing things in our own strength? Being good people...

Previously, when I've looked at this and asked God for confirmation, I came across this verse:

Galatians 4 - And because we are his children, God has sent the Spirit of his Son into our hearts, prompting us to call out, “Abba, Father.”

That gave me Peace, as He is who my heart cries out for! And when I do go to Him, He does provide that Peace :-)

....But then, is this any different to the new age prayer who prays to whatever they think is God?!?  

I don't know what I'm looking for - as I know that even casting out demons or miracles are not true 'evidence' either. (Matthew 7: 21+)

Well, regardless, I am still going to continue following Him and His Word - to who else would we go right?? :-) And I hunger to hear from Him more. God knows that I am seeking this at this time....

Would be interested to hear your thoughts?
