Jessie Penn-Lewis’s book Thy Hidden Ones showed me God’s purpose in my isolation and helplessness. It was her words I sent in a letter to Jim: “In the Holy Spirit’s leading of the soul through the stripping of what may be called ‘consecrated self,’ and its activity, it is important that there should be a fulfillment of all outward duty, that the believer may learn to act on principle rather than on pleasant impulse.” It was a spiritual lesson that was to fortify me through countless later experiences when feelings or impulses contributed nothing to an inclination toward obedience. God allows the absence of feeling or, more often, the presence of strong negative feeling that we may simply follow, simply obey, simply trust.
