Re: Your statement, "It is not the experience themselves that I seek, but the intimacy with God."
I'd recommend: The Inner Man of the Heart Or, the Believer's Sphere of Life and Base of Operations.
by T. Austin-Sparks 1926.

There are also numerous other books by this author at the following website: http://www.austin-sparks.net/english/books/books_alpha.html
In regard to his own ministry this man T. Austin-Sparks, wrote these words -
"The object of the ministry is to contribute to the Divine end which is presented in the words of Ephesians 4:13 - "...till we all attain unto the unity of the faith, and of the knowledge (literally - full knowledge) of the Son of God, unto a full-grown man, unto the measure of the stature of the fulness of Christ: that we be no longer children..."
It is not connected with any 'Movement,' 'Organization,' 'Mission' or separate body of Christians, but is just a ministry to "all saints." Its going forth is with the prayer and hope that it will so result in a fuller measure of Christ, a richer and higher level of spiritual life, that, while bringing the Church of God into a growing approximation to His revealed will as to its 'attainment,' the Church may be better qualified to be used of Him in testimony in the nations, and to the completing of its own number by the salvation of those yet to be added by the Lord."
Re: Your statement, "There is obviously much error to steer clear from."
Yes! There is! So please be sure and read Ted Brooks' book first.
Hope these will be profitable and edifying to your spirit.
