(We must [pass] through great sadness), 146, is a cantata by Johann Sebastian Bach, a church cantata for the third Sunday after Easter. Bach composed it in Leipzig in 1726 or 1727.

History and words 
Bach composed the cantata in Leipzig for the Third Sunday after Easter, called Jubilate. The prescribed readings for the Sunday were from the First Epistle of Peter, "Submit yourselves to every ordinance of man" (), and from the Gospel of John, Jesus announcing his second coming in a Farewell discourse (). Bach contrasted sorrow and joy in earlier cantatas for the same occasion, first in Weimar in 1714, , then in Leipzig in 1725, . The unknown poet chose a quote from  to begin the cantata, "We must through much tribulation enter into the kingdom of God", which Salomon Franck had already used for the first recitative of . The three following movements deplore the sufferings in the world, whereas three more movements depict the joyful hope for a better life in the Kingdom of God. The theme throughout his texts is a longing for death. Movement 5 is a paraphrase of , which Brahms also chose for his Requiem, "They that sow in tears shall reap in joy". Movement 6 refers to , "For I reckon that the sufferings of this present time are not worthy to be compared with the glory which shall be revealed in us". Only the music but not the words of the closing chorale is extant. The ninth stanza of Gregorius Richter's hymn "" has been suggested by Alfred Dürr as a possible text for this closing chorale. Klaus Hofmann suggested "" by Christoph Demantius.

The earliest possible date for the first performance is 12 May 1726. 4 May 1727 is another possibility.

Music 

Two movements of the cantata, the Sinfonia and the first movement, are related to Bach's Harpsichord Concerto in D minor, BWV 1052, which was possibly derived from a lost violin concerto. The original music for the cantata is also lost, but scholars are convinced that it is a work of Bach. He used an instrumental concerto in a similar way for movements of his cantatas , and , where his authorship is beyond doubt.

Bach reworked the first movement of the harpsichord concerto to an organ concerto, expanding the strings by woodwind instruments. He changed the second movement to a choral movement by embedding vocal parts in the music, but this time without additional woodwinds. Brian Robins commented: The opening chorus is superimposed onto the deeply moving slow movement of the concerto, the anguish of the repeated (ostinato) bass line ideally underlining a text concerned with the tribulation that must be endured before the kingdom of heaven is attained. Musicologist Julian Mincham describes the process of changing a harpsichord concerto movement to a chorus with obbligato organ in detail: The original thirteen-bar throbbing ritornello theme is retained but its function has changed. The voices soar above it from the very first bar and continue to enhance it throughout its six appearances in different tonal environments. The ritornello theme has virtually become a free "ground bass" throughout. The tortuous melodic line, the main focus of attention in the concerto setting, has now become an obbligato melody of secondary significance. It is played by the organ, the first time Bach has used the instrument in this way in a chorus. The choir rises magnificently above everything else establishing itself as the dominant musical force, even appearing to disregard the phrasing of the original composition. All that was of primary importance in the concerto is now secondary to the chorus and its message. This momentous adagio, seemingly complete in its version for strings and harpsichord, has taken on a whole new dimension of musical meaning.

Hofmann summarizes: "Filled with lamenting in the spirit of the Passion, the movement gains its intensity from the dense and dissonant harmonic expressiveness, and incorporates ostinato phrases whose regular appearances seem to illustrate inevitability."

The third movement is an alto aria with violin obbligato, which transcends "" (towards Heaven). The following recitative, a lament on the persecution in the world, is accompanied by long chords of the strings. Movement 5 illustrates in two sections the opposition of sowing with tears and reaping with joy, accompanied by a flute and two oboes d'amore. Movement 7 is probably derived from a secular dance-like movement in da capo form. A ritornello frames the first section, continuo only accompanies the middle section. The final chorale is set for four parts on the melody of "".
