I feel it almost impossible to say anything (in my comfort and security -- apparent security, for real security is in Heaven and thus earth affords only imitations) which would not sound horribly false and facile. Also, you know it better than I do. I should in your place be (I have in similar places been) far more panic-stricken and even perhaps rebellious. For it is a dreadful truth that the state of (as you say) "having to depend solely on God" is what we all dread most. And of course that just shows how very much, how almost exclusively, we have been depending on things. But trouble goes so far back in our lives and is now so deeply ingrained, we will not turn to Him as long as He leaves us anything else to turn to. I suppose that all one can say is that it was bound to come. In the hour of death and the day of judgment, what else shall we have? Perhaps when those moments come, they will feel happiest who have been forced (however unwittingly) to begin practicing it here on earth. It is good of Him to force us; but dear me, how hard to feel that it is good at the time."
