spoudē

Twice in the New Testament this word simply means speed. Both times it sits in the same everyday phrase, the ancient equivalent of "in a hurry," and both times it describes someone covering ground fast: the girl rushing back into Herod's banquet with her request, and Mary setting out for the hill country after the angel's visit.

This is the older and more literal side of the word. It grew out of the verb for hurrying (σπεύδω), and Greek writers used the noun for the speed of a messenger, an army, or a ship. The ancient Greek translators of the Old Testament used it the same way, for Israel eating the Passover dressed and ready to leave Egypt at a moment's notice.

Speed and earnest effort are not far apart. Someone who cares urgently about a thing moves on it at once, which is why one Greek word covers both. Still, this literal sense accounts for only two of the word's twelve appearances; the second meaning below is the one a reader meets far more often.

Ten of this word's twelve New Testament appearances have nothing to do with going anywhere quickly. They describe someone who cares about a matter enough to put real work into it, and to put that work in now. English has no single word for that combination. "Diligence" catches the work but sounds slow and dutiful. "Eagerness" catches the warmth but sounds like a feeling rather than labor. "Zeal" pulls toward the burning heat of a different word (ζῆλος). The Greek holds all of it at once: willing, energetic, prompt commitment.

The senses below trace where that energy is aimed. It can go into a job someone has taken on, it can describe the sort of person they are, and it can be directed at particular people. Paul's letters to Corinth show the last of these most plainly: he thanks God for putting into Titus the same energetic concern for the Corinthians that he carries himself.

Two neighboring words help fix its edge. Wearying labor (κόπος) names the toil and what it costs the worker; a ready willingness (προθυμία) names the eagerness before anything has been done. This word sits between them, as eagerness already in motion, and its matching verb (σπουδάζω) is what someone is doing when they "make every effort."

In the letters this energy is never treated as a temperament some believers happen to have and others do not. It is asked for, thanked for, and traced back to what God has put in a person's heart.
