'Instruments In The Redeemer's Hand' by Paul David Trip........excellent and an absolute reread.
Paul Trip is steadily becoming a favorite in our home.
'Doing Things Right In The Matter Of The Heart' by John Ensor......good but hard to follow.
'The Enemy Within' Lungard........eye-opening and heart cutting analysis, a reread. For those who struggled with John Owen. Buy several copies and give them away.
