8:1 do you to wit. The words “do you to wit,” a common expression in Elizabethan England, would be rendered “make you to be aware of” in modern English.

8:1 grace. The “grace” mentioned here is not in reference to salvation, but to Christian character, which should exhibit many Christian graces in word (e.g., Colossians 4:6) and deed (e.g., II Corinthians 9:8), as well as the Christian life as a whole (e.g., II Peter 3:18). In I Corinthians 8 and 9, Paul is especially referring to “this grace also” (II Corinthians 8:6-7), meaning the grace of giving.

8:1 churches of Macedonia. The “churches of Macedonia” included Thessalonica and Berea, and especially the church at Philippi, from which Paul was writing and sending this second letter to the churches of Achaia, notably that at Corinth.

8:2 their joy. The grace of joy accompanies the grace of giving, especially when both are refined in the furnace of affliction and poverty. This is one of the paradoxes of the genuine Christian life. Like the widow and her mite (Mark 12:41-44), the Philippians “first gave their own selves to the Lord” (II Corinthians 8:5), and then could share generously with others, since they naturally regarded their possessions also as belonging to the Lord. Therefore, the Apostle could promise them that God would “supply all your need according to His riches in glory by Christ Jesus” (Philippians 4:19). Much of Paul’s teaching in this and other epistles on the matter of Christian giving centered on a collection for the impoverished Christians in the “mother church” at Jerusalem, but the principles apply to Christian stewardship and Christian giving in general. See notes on I Corinthians 16:1-3.

8:6 this same grace. Note that giving and sharing of one’s means is called a “grace”—just as faith, love, etc. (note II Corinthians 6:7).
