All Means All!
I have pondered this verse lately, and have found that it feeds my spirit. All does not mean “all – except the paths I am walking in now,” or “nearly all – except this especially difficult and painful path.” All must mean all. So, your path with its unexplained sorrow or turmoil, and mine with its sharp flints and briers – and both our paths, with their unexplained perplexity, their sheer mystery – they are His paths, on which he will show himself loving and faithful. Nothing else; nothing less.
