My reading has entered Jeremiah. In his "call story", Jeremiah objects to God, saying, "I do not know how to speak, for I am only a boy" (1.6). The LORD replies: "Do not say, 'I am only --'" (1.7). It is the language of limits to say that "I am only --". It doesn't matter what we "only" are, because we are never alone. When God is for us, "who can be against us"? (Romans 8.31).
