Ephesians 5:1-14: "1 Therefore be imitators of God, as beloved children. 2 And walk in love, as Christ loved us and gave himself up for us, a fragrant offering and sacrifice to God.
"3 But sexual immortality and all impurity or covetousness must not even be named among you, as is proper among saints. 4 Let there be no filthiness nor foolish talk nor crude joking, which are out of place, but instead let there be thanksgiving. 5 For you may be sure of this, that everyone who is sexually immoral or impure, or who is covetous (that is, an idolater), has no inheritance in the kingdom of Christ and God. 6 Let no one deceive you with empty words, for because of these things the wrath of God comes upon the sons of disobedience. 7 Therefore do not become partners with them; 8 for at one time you were darkness, but now you are light in the Lord. Walk as children of light 9 (for the fruit of light is found in all that is good and right and true), 10 and try to discern what is pleasing to the Lord. 11 Take no part in the unfruitful works of darkness, but instead expose them. 12 For it is shameful even to speak of the things that they do in secret. 13 But when anything is exposed by the light, it becomes visible, 14 for anything that becomes visible is light. Therefore it says, 'Awake, O sleeper, and arise from the dead, and Christ will shine on you.'"
Ephesians 3:16-19: "16 that according to the riches of his glory he may grant you to be strengthened with power through his Spirit in your inner being, 17 so that Christ may dwell in your hearts through faith - that you, being rooted and grounded in love, 18 may have strength to comprehend with all the saints what is the breadth and length and height and depth, 19 and to know the love of Christ that surpasses knowledge, that you may be filled with all the fullness of God."
Ephesians 4:3-6: "3 eager to maintain the unity of the Spirit in the bond of peace. 4 There is one body and one Spirit - just as you were called to the one hope that belongs to your call - 5 one Lord, one faith, one baptism, 6 one God and Father of all, who is over all and through all and in all."

The passage from Ephesians 5 is the primary source for the hymn text. The end of verse 14 is paraphrased in the first half of the first verse ("Awake, O sleeper, rise from death, / And Christ shall give you light") and, along with verse 2, is referred to in the hymn's last verse ("For us Christ lived, and for us He died... Awake, arise, go forth in faith."). Verse 2 also appears at the beginning of the third verse: "Then walk in love as Christ has loved."
The passage from Ephesians 3 (specifically verses 18-19) is referred to at the end of the first verse: "So learn His love, its length and breadth, / Its fullness, depth, and height."
The passage from Ephesians 4 (particularly verse 3) appears at the end of the second verse: "He came... To give the Spirit's unity, / The very bond of peace."
