I've been filled with the Holy Ghost now for over 30 years. I've seen many young preachers grow up and make lots of mistakes. I seen some of them rise to the top and fall years later. I've seen young ladies who love the Lord fall in love with someone who isn't saved and painfully deal with the consequences of their choices.
Being filled with the Holy Ghost is just the beginning. Now that you have received birth from above, of course with evidence, you need to learn how to give your body to the Lord as a living sacrifice, and work to transform your thinking.
Both of these are easily taken care of if you walk in the Spirit. However, remaining in the spirit should be the goal you seek and here is why!
