(Keep Jesus Christ in mind), 67, is a church cantata by Johann Sebastian Bach. He composed it in Leipzig for , the first Sunday after Easter, and first performed it on 16 April 1724. Based on the prescribed gospel of the appearance of Jesus to the Disciples, first without then with Thomas, an unknown poet compares the situation of the doubtful Thomas to the Christian in general. He places Nikolaus Herman's Easter hymn "" in the centre of the cantata, repeats the line "" (Peace be with you) several times, and ends with the first stanza from Jakob Ebert's hymn "" (Thou Prince of Peace, Lord Jesus Christ). Bach structured the work in seven movements, arranged in symmetry around the central chorale, and scored it for three solo voices, a four-part choir and a Baroque instrumental ensemble of a slide horn for hymn tunes, flauto traverso, two oboes d'amore, strings and basso continuo. Besides the unusual central chorale, the cantata contains a dramatic scena with Jesus repeating "Peace be with you" against the enemies.

The poet sees Thomas as similar to the doubtful Christian in general, whose heart is not at peace. The center of the cantata is the Easter hymn "" (The glorious day has appeared) by Nikolaus Herman (1560), praising the day of the resurrection. In contrast, movement 5 recalls the danger by the enemies, until in movement 6 Jesus appears, as he did to his disciples in Jerusalem, finally bringing peace.
