Biblical citations in the hymnal: John 6:68-69, Acts 4:12
John 6:68-69: "68 Simon Peter answered him, 'Lord to whom shall we go? You have the words of eternal life, 69 and we have believed, and have come to know, that you are the Holy One of God.'"
Acts 4:12: "And there is salvation in no one else, for there is no other name under heaven given among men by which we must be saved."

Acts 4:12 appears in the first two verses, mostly in the first half of each:
Seek where you mayTo find a wayThat leads to your salvation.My heart is stilled,On Christ I build,He is the one foundation.
Seek whom you mayTo be your stay,None can redeem his brother.All helpers failed;This man prevailed,The God-man and none other,
The text from John 6 could be cited for those verses too, but it (specifically "You have the words of eternal life") also seems to appear near the end of the fourth verse: "You are my Lord; / Your precious Word / Shall guide my way."
+++
The first verse ends with the lines "He overthrows / All evil foes; / Through Him I more than conquer," and the fourth verse contains the lines "Not wealth nor pride / Nor fortune's tide / Our bonds of love shall sever," and these sections draw from Romans 8:37-39: "37 No, in all these things we are more than conquerors through him who loved us. 38 For I am sure that neither death nor life, nor angels nor rulers, nor things present nor things to come, nor powers, 39 nor height nor depth, nor anything else in all creation, will be able to separate us from the love of God in Christ Jesus our Lord."
