Ed McCully (1927–1956) was an evangelical Christian missionary to Ecuador who, along with four others — Jim Elliot, Pete Fleming, Nate Saint, and Roger Youderian — was killed while attempting to evangelize the Huaorani people through efforts known as Operation Auca.
Letter to Jim Elliot, September 22, 1950, during his time as a law student and working as a hotel night clerk 
- Since taking this job things have happened. I've been spending my free time studying the Word. Each night the Lord seemed to get hold of me a little more. Night before last I was reading in Nehemiah. I finished the book, and read it through again. Here was a man who left everything as far as position was concerned to go do a job nobody else could handle. And because he went the whole remnant back in Jerusalem got right with the Lord. Obstacles and hindrances fell away and a great work was done. Jim, I couldn't get away from it. The Lord was dealing with me. On the way home yesterday morning I took a long walk and came to a decision which I know is of the Lord. In all honesty before the Lord I say that no one or nothing beyond Himself and the Word has any bearing upon what I've decided to do. I have one desire now - to live a life of reckless abandon for the Lord, putting all my energy into it. Maybe He'll send me someplace where the name of Jesus Christ is unknown. Jim, I'm taking the Lord at His word, and I'm trusting Him to prove His Word. It's kind of like putting all your eggs in one basket, but we've already put our trust in Him for salvation, so why not do it as far as our life is concerned? If there's nothing to this business of eternal life we might as well lose everything in one crack and throw our present life away with out life hereafter. But if there is something to it, then everything else the Lord says must hold true likewise. Pray for me, Jim.
- Man, to think the Lord got hold of me just one day before I was to register for school! I've got money put away and was all set to go. Today was registration day so I went over to school to let them know why I wouldn't be back. I really prayed like the apostle asked the Ephesians to pray, that I might "open my mouth boldly." I talked to all the fellows that I knew well. Then I went in to see a professor I thought a lot about. I told him what I planned to do, and before I left he had tears in his eyes. I went in to see another professor and talked to him. All I got was a cold farewell and a good luck wish.
- Well, that's it. Two days ago I was a law student. Today I'm an untitled nobody. Thanks, Jim, for the intercession on my behalf. Don't let up. And brother, I'm really praying for you too as you're making preparation to leave. I only wish I were going with you.
