Continue in prayer — persevere, do not give up. Watch — stay alert, attentive. With thanksgiving — grateful even while asking. Three dimensions of healthy prayer.

The same triad recurs throughout Paul's letters. Prayer is to be persistent (Luke 18:1), watchful (Matthew 26:41), and thankful (Philippians 4:6). The believer who prays this way does not faint.

A door of utterance. Paul, imprisoned, asks not for release but for opportunity to preach. His concern is the open door for the gospel, not the open door of his cell.

A model for prayer about ministry. Pray for open doors — God-given opportunities to share Christ. And note Paul's priority — even in chains, his concern is the advance of the gospel, not his own comfort.

Them that are without — those outside the faith. The believer's conduct toward unbelievers requires wisdom — careful, thoughtful living that commends the gospel rather than discrediting it.

Redeeming the time — buying up the opportunity. Greek exagorazomenoi ton kairon. Time and opportunity are limited resources to be used strategically for the kingdom. The wise believer makes the most of every chance.

Speech... seasoned with salt. Salt preserves and flavors. The believer's speech should be gracious yet have substance and bite — not bland, not corrupt, but wholesome and engaging.

That ye may know how ye ought to answer every man. Gracious, salted speech equips the believer to respond well to each person's questions and objections. 1 Peter 3:15 — be ready always to give an answer. The preparation is partly a matter of cultivated speech.

Labouring fervently for you in prayers. Greek agonizomenos — agonizing, wrestling, striving. Epaphras prayed for the Colossians with the intensity of an athlete in contest. Intercession can be hard labor.

A model intercessor. Epaphras prayed with effort and aim — that ye may stand perfect and complete in all the will of God. His prayers were specific and earnest, targeting their spiritual maturity. This is what serious intercession looks like.

Two names side by side, with very different futures. Luke, the beloved physician — faithful to the end, the writer of the Gospel and Acts, who stayed with Paul (2 Timothy 4:11). Demas — who would later forsake Paul, having loved this present world (2 Timothy 4:10).

A sobering pairing. Two men named in the same breath; one finished well, one fell away. Present association with the faithful is no guarantee of future faithfulness. Each man must endure to the end himself.
