John 3:8 The wind bloweth where it listeth, and thou hearest the sound thereof, but canst not tell whence it cometh, and whither it goeth: so is every one that is born of the Spirit.
Being born again in the spirit is a whole new experience and the first touches of the Holy Spirit trying to communicate with you will be just like this verse. You can feel it but cannot see it. You hear the sound of it but those first few moment of contact might very well be filled with doubt. What was that?
It is all new to you and this Holy Spirit is God and how Jesus Christ and God the Father have chosen to communicate with us. He is that still small voice from 1 Kings 19:12 which is an excellent reminder about how and where we look for God. Having been given spiritual eyes and ears takes some training to ignore our old ones in favor of the new.
2 Corinthians 5:7 (For we walk by faith, not by sight:)
Spiritual training is discipleship. It is one mature Christian helping a new Christian figure out how this all works together. There are many different discipleship classes out there but they all have the same goal, spiritual training. That covers a vast array of disciplines, subjects, and developmental techniques. I have my own personal discipleship method based on my prophetic gift. Not all Christians have that gift and a standard has to be set that works for everyone.
Hopefully every disciple will come to understand how to use those spiritual eyes and ears. No one can predict how long that will take but the goal is to discover the Holy Spirit that resides in you and leads you in all truth.
