My Aunt and Uncle were somewhat among the pioneers of the Holy Spirit revival.They have been with the Lord for some yrs now.Kenneth Hagin Sr sat under their ministry as well as younger ones such as Copeland coming to them when they set out for ministry.I bring this up because their books are no longer in publication but when I was first saved in 1980 I had them and bought Kenneth Hagins books{in bible college we used his workbook}and I'd think there still in the stores.They are great and really right on target.But you asked about websites.Faithoutreach.com{Hagin},Joycemeyer.org,and I'll give u more addresses if u like.I feel sure that Hagin Jr at least has study books in u'r local christian bookstore and his teachings would be the same as his dad's.I hope they have them,I had them on the gifts of the spirit and faith and others.Probably can get them from their sites.Mine have all been lost or stolen in many moves but would sure like to replace them.Love,Dot.
