verse 15 is heightened by the imperative command in verse 17 to “become” or “be” (or even “prove yourselves”) “not unwise.” Sounding a definite warning to avoid foolishness and the dangers that the enticing ways of the “unwise” present, verse 17 rephrases Paul’s earlier urgings in verses 9 and 10. The “will of the Lord” is the standard for all Christian behavior. Disregard or disobedience will be evident by ensuing “unfruitful works of darkness.”
