This document discusses the importance of preparing for judgment and doing our duty to God. It notes that we will all be judged according to God's commands and what is in our hearts. To fear God, we must know His power and justice, keep His commands through faith in Christ, and love both God and our neighbors. The judgment will come unexpectedly, so we must start doing our duty now by believing, repenting, confessing, and being baptized in order to be saved.
