"But I tell you that I am going to do what is best for you. That is why I am going away. The Holy Spirit cannot come to help you until I leave. But after I am gone, I will send the Spirit to you." John 16:7 (CEV)
If you decide to believe and follow Jesus, then the Holy Spirit is available to you. The Holy Spirit is God living with you, guiding, comforting, strengthing, interceding for you, and caring for you. Pray to God that you would receive the Holy Spirit, or you may ask someone to pray that you would receive it.
The Holy Spirit enables you to speak the words of Jesus, gives you a heavenly language, the ability to heal, to prophecy, etc... The Holy Spirit works through you to bring God's Kingdom to this planet.
