It is free, but it costs everything

Kathryn Kuhlman said many times "its not sliver vessels he needs, is not golden vessels he wants, its yielded vessels…"she on one occasion stayed silent and all you could hear was the sound of her weeping quietly "…that’s all…" she continued "…that’s all." 

"It costs much but it’s worth the cost, it costs everything but it’s worth everything"
