My prose translation:
1 Preserve Your teaching for us,Lord, to the last time;Preserve Your kingdom; increaseYour noble Christendom;Preserve steadfast faith,The light of the guiding star of hope;Let Your word not be taken away from usIn this vale of tears.2 Preserve Your glory and resistThose who speak against You;Enlighten, Lord, and convert,All-knowing, eternal Light,Those who did not know You so far;Discover still of the world(Of which You are called the Light)Those who please You.3 Preserve what You have builtAnd bought by Your blood,What You trust in for Yourself,The church, on which runsThe fierce storm of the dragon;May You be her protection and rampartSo that, if the world will burst,She will nevermore fall.4 Preserve, Lord, Your sheep;The fierce wolf approaches;Wake from Your sleepBecause no one can saveWithout You, You great shepherd.Lead us on good pasture,Guide, nurture, gladden, feedUs in the desolate heath.5 Preserve us, Lord, Your heirs,Your dear sacred ones;Tear, smash, ruinWhatever is against Your glory.Let Your law lead us;Allow us Your bread of Heaven;Let Your jewelry adorn us;Heal us by Your death.6 Preserve and let us hearYour word, which makes blessed,The mirror of Your glory,The light in this night;So that this well waters us,The dew of Heaven moistens us,So that this guiding principle pilots;The honey delights.7 Preserve in storm and wavesYour household; let notWind and weather cut us down;Pilot Your ship Yourself and directIts course, so that we reachThe haven after the timeAnd help us spread the sailIn blessed eternity.Adam Greigen, +1660.
I translated "widerspricht" in the second verse as "speak against," which is somewhere in between my dictionary's suggestions of contradict and oppose. At the end of the verse, I translated "was einig dir gefällt" as "those who please You," but it's literally something more like "what few please You."
"Erwach aus deinem Schlafe" ("wake from Your sleep") in the fourth verse sort of contradicts Psalm 121:4: "Behold, he who keeps Israel will neither slumber nor sleep." For "treib" later in the verse, my dictionary suggested "drive," but this seemed too intense for this context, so I translated it as "guide."
For "Heiligthum" in the fifth verse, my dictionary suggested "(holy) shrine," "(sacred) relic," and "something sacred." I translated it as "sacred ones."
This hymn appears as "Preserve Thy Word, O Savior" in The Lutheran Hymnal (#264), albeit with the fourth verse omitted. As far as I can tell, it's not in Lutheran Worship or The Lutheran Service Book. The Gesangbuch notes that the text is sung to the tune "Herzlich thut mich verlang[en]." Here's the TLH arrangement:
