will: what someone has decided shall be, whether a purpose, a desire, or a command
At its core this word names what a person determines, wants, or intends to come about. Around four out of five times in the New Testament it is the will of God, and there it covers a wide span:
- God's settled saving purpose
- the moral life God asks of people
- the mission the Father gives the Son
The same word also names ordinary human wanting and the disordered cravings of fallen people. These are not separate words but one word taking its color from its setting, above all from the phrase "the will of God."
The senses below are not airtight compartments. The word usually points to the content of what is willed (the plan, the command, the thing wanted) rather than to the bare faculty of wanting, but a few places lean the other way, and the line between God's sovereign purpose and God's moral demand is often deliberately blurred. The Lord's Prayer petition "your will be done" reaches for both at once: that God's purpose be accomplished and that people do what God asks.
The word's weight is borrowed, not built in. Greek writers before the Bible used it rarely, sometimes for mere appetite. The Greek Old Testament made it the standard rendering of two Hebrew words for delight (חפץ) and favor (רצון), and so handed the New Testament writers a ready-made term for the gracious purpose and pleasure of God.
