1 John 5:5-8: "5 Who is it that overcomes the world except the one who believes that Jesus is the Son of God?
"6 This is he who came by water and blood - Jesus Christ; not by the water only but by the water and the blood. And the Spirit is the one who testifies, because the Spirit is the truth. 7 For there are three that testify: 8 the Spirit and the water and the blood; and these three agree."
John 10:10: "'The thief comes only to steal and kill and destroy. I came that they may have life and have it abundantly.'"

The passage from 1 John 5 is the basis for the hymn and appears most clearly in the first and fifth verses. John 10:10 appears in the line "Life has come, with life for all," which occurs at the end of both of these verses.
The third verse ends with the lines "[Christ] spreads a table where He feeds us / With His body and His blood." While this clearly refers to the Lord's Supper, the language recalls Psalm 23:5: "You prepare a table before me in the presence of my enemies; you anoint my head with oil; my cup overflows."
Part of the fourth verse ("God, His two-edged sword unsheathing, / By His Spirit life is breathing / Through the living, active Word.") comes Hebrews 4:12 ("For the word of God is living and active, sharper than any two-edged sword, piercing to the division of soul and of spirit, of joints and of marrow, and discerning the thoughts and intentions of the heart.") and possible also Ephesians 6:17 ("and take the helmet of salvation, and the sword of the Spirit, which is the word of God").
