Gary Wilkerson writes this concerning his father which helps to clarify what I meant with the above:
At his vulnerable times, my father wondered whether he was loved by God at all. He didn't wonder why people suffer (And his family suffered as much as any. Through a genetic anomaly, my mother, both sisters, a niece, and now a nephew all have faced serious battles with cancer.). Very simply, my father wondered his whole life whether God loved him. It was a question he kept mostly to himself. Growing up, he had absorbed some of the traumatizing aspects of a theology that leaned toward works and legalism and sometimes fear. Although doctrinally he knew he was free in Christ, something in him still made him feel he had to work hard - that nothing he did was enough, that more was required to fill what was missing in his righteousness in Christ.
My uncle Don, who for years worked alongside my dad in ministry, observes, "David had a lot of grace for other people, but he wasn't always able to appropriate it for himself."
[---] The revelation of my father's lifelong struggle was stunning to many. "I preached a lot about the love of God nowadays, and it was David who had the greatest influence on me for that," says Bob Phillips, who copastored with my father at Times Square Church. "It's based on what I learned from him in his years as a pastor, not just from his preaching but from how he believed and lived." Like so many others who worked closely with my dad, Bob never would have guessed this struggle to be my father's deepest.
From the outside, those who understood my dad's early life would say he never stood a fighting chance. Yet, characteristic of my fahter, a few decades ago he set himself on a journey to correct things within himself. At that time, in the eighties, he was still busy traveling the world as an evangelist. Yet his own soul was dry; he had become weary of preaching the same messages to crusade audiences. Between those events, he began reading a stack of books given to him by a discerning friend, author and preacher Leonard Ravenhill. These were classic works that had endured the centuries, most of them written by Puritans, names many of us have never heard of. As my father dug into those treasures, his heart opened to a new revelation of Christ. Grace awakened in him, coming alive in a way he had never known. The old books stirred him once again to study the Scriptures cover to cover, this time with a new understanding of the gospel. As he explored the full extent of the finnished work of Christ, he experienced joy.
Toward the end of his life, my father confided to me that he still struggled to know whether he was loved. He couldn't escape completely the emotional cobwebs, but he was seeing more and more clearly the work that Jesus had done for him. In my last conversation with him, he told me how deeply he had probed, how he had scoured every page of every writing he could find on the glorious subject of God's covenant grace. And yet I could see in his eyes there was a yearning for more. There were things he still wanted to know about the depth and breadth of Christ's finnished work. That's when he urged me to dig deeper in my own search on the subject, not to be satisfied but to go farther. It was as if he was saying, "I got a late start. I want you to have it better. I want my grandchildren to have it better. Don't ignore this truth, If you catch it now, it can save you years. Son - do you see?"
