I. "Amen" is a word of which all the associations are, or ought to be, interesting. (1) With this word did our Lord Jesus Christ Himself introduce most of His most impressive revelations. By this term, expressing certainty, faithfulness, unchangeable truth, He embodied in daily utterance that which on one occasion at least He expanded into a doctrine "Verily, verily, I say unto thee, We speak that we do know, and testify that we have seen" with a positiveness of intuition and insight belonging to Him, and to Him only, who is at once He that came down from heaven and the Son of man who is in heaven. (2) In this word does St. Paul gather up the whole sum of the revelations of Christ and say, "All the promises of God in Him are Yea, and in Him Amen." (3) By this same word does the beloved disciple St. John actually designate the very person of his Master: "These things saith the Amen," etc.
II. The force and significance of the word must vary: (1) with the place in which it occurs in our services; (2) according to the mind of the worshipper by whom it is used.
III. The conditions of joining rightly in this particular part of our service are the same with those which we know to be the conditions of public worship in general. You must be desirous of meeting God. You must be desirous of finding God. You must come with that desire and stay with that desire.
