Who are the missionaries and godly men who were helped by Keswick Theology for a fuller Christ like life and ministry? My curiosity arises from two sources.

J I Packer ( Reformed Theology ) says the Keswick Theology ruined him  

Whereas 

T Austin Sparks says that the Keswick Theology helped him lead a fuller life  

Since reformed theologians are against Keswick Theology, I would like to get a list of missionaries and godly men who were helped by Keswick Theology for a fuller Christ-like life and ministry so that I can study their lives.
Some people I came to know are Hudson Taylor, Amy Carmichael, Oswald Chambers &amp; Billy Graham. 

Source: What is the Keswick movement, and is it biblical? 

This letter of Hudson Taylor tells us how he experienced the second blessing.
