Much as your spirit leads you in the ways you go, when you have the Holy Spirit, he shows you things of God, as it is literally God's spirit within you; sharing space. So now, once you put your trust in Christ, you are given this Spirit, which discerns things of God, as you have God within you. God has a great and good path for you planned out, and the Holy Spirit can lead you in that path if you allow him; much as he did for Christ. Christ received the Spirit and then was led by him into the desert. Down this path you will find hardship, trials, and tribulation, but God will cleanse you of sin that you've lived in and will give you freedom from it. It's not to say that you won't ever sin, but while he has justified you, you are being cleansed.
This Holy Spirit also comes with the power to overcome many difficulties, to yes, do miracles as God wills it, but the most important thing is that now you can come directly before him and know him personally and him you. If you draw close to God, he will to you, and if you work within his Holy Spirit, he will continue to give you more and more to handle; to strengthen you and make you more of the one he designed you to be. Furthermore, as you read the scriptures, the Holy Spirit will reveal deep meanings within the words of the bible that apply to your life as a Christian, and this will continue to happen no matter how many times you read the bible. You'll always find some new and amazing thing about God through this spirit.
I've had the spirit work through me to do many miraculous things, but the things I treasure most is the discernment when speaking with non-believers and the ability to relate the gospel in a peaceful way; unlike many on here unfortunately. I would suggest that you take some time and separate yourself from distraction and just take a moment to really dig into the bible and the character of God. Learn who he says he is firsthand.
