Ephesians 6:8

6:8 because you know that each person, whether slave or free, if he does something good, this ¹  will be rewarded by the Lord.

Ephesians 2:10

2:10 For we are his workmanship, having been created in Christ Jesus for good works that God prepared beforehand so we may do them. ² 

Ephesians 3:18

3:18 you may be able to comprehend with all the saints what is the breadth and length and height and depth, ³ 

Ephesians 4:28-29

4:28 The one who steals must steal no longer; rather he must labor, doing good with his own hands, so that he may have something to share with the one who has need. 4:29 You must let no unwholesome word come out of your mouth, but only what is beneficial for the building up of the one in need, ⁴  that it may give grace to those who hear.

[6:8]  ¹ sn The pronoun “this” (τοῦτο, touto) stands first in its clause for emphasis, and stresses the fact that God will reward those, who in seeking him, do good.

[2:10]  ² tn Grk “so that we might walk in them” (or “by them”).

[3:18]  ³ sn The object of these dimensions is not stated in the text. Interpreters have suggested a variety of referents for this unstated object, including the cross of Christ, the heavenly Jerusalem (which is then sometimes linked to the Church), God’s power, the fullness of salvation given in Christ, the Wisdom of God, and the love of Christ. Of these interpretations, the last two are the most plausible. Associations from Wisdom literature favor the Wisdom of God, but the immediate context favors the love of Christ. For detailed discussion of these interpretive options, see A. T. Lincoln, Ephesians (WBC), 207-13, who ultimately favors the love of Christ.

[4:29]  ⁴ tn Grk “but if something good for the building up of the need.” The final genitive τῆς χρείας (th" creia") may refer to “the need of the moment” or it may refer to the need of a particular person or group of people as the next phrase “give grace to those who hear” indicates.
