“All those for whom I have affection I reprove and discipline. Therefore be zealous and repent.” (Revelation 3:19) As with discipline from Jehovah, Jesus’ discipline is a sign of his love. (Hebrews 12:4-7) The Laodicean congregation should take advantage of his affectionate concern and apply his counsel. They should repent, recognizing that their lukewarmness amounts to sinning. (Hebrews 3:12, 13; James 4:17) Let their elders put materialistic ways behind them and “stir up like a fire” the gift they have from God. With the spiritual eye salve taking effect, let all in the congregation find refreshment as from a cooling draft of cold springwater.​—2 Timothy 1:6; Proverbs 3:5-8; Luke 21:34.

17. How can wealth be spiritually dangerous to us?

¹⁷ We must not allow materialism, riches, or the lack of riches to make us lukewarm. Wealth can aid in opening up new possibilities of service, but it can also be dangerous. (Matthew 19:24) A well-to-do person may feel that he does not need to be as zealous in the preaching work as others, provided that he makes sizable donations from time to time. Or he may feel that being wealthy entitles him to favors. Additionally, there are many pleasures and pastimes open to a wealthy person that others cannot afford. But those diversions take up time and may draw the unwary away from the Christian ministry, thus making the indiscreet one lukewarm. May we avoid all such snares and keep “working hard and exerting ourselves” wholeheartedly, with everlasting life in view.​—1 Timothy 4:8-10; 6:9-12.

‘Taking the Evening Meal’

18. What opportunity does Jesus set before the Christians in Laodicea?

¹⁸ Jesus goes on to say: “Look! I am standing at the door and knocking. If anyone hears my voice and opens the door, I will come into his house and take the evening meal with him and he with me.” (Revelation 3:20) If the Laodicean Christians will only welcome Jesus into their congregation, he will help them to overcome their lukewarmness!​—Matthew 18:20.

20. (a) At the beginning of the Lord’s day, what resulted from Christendom’s lukewarmness? (b) How has Jesus’ judgment affected Christendom?

²⁰ Jesus’ loving exhortation to the Laodiceans has great significance for the remaining anointed Christians today. Some of these remember that, as the Lord’s day began, Christendom’s religionists were lukewarm to an appalling degree. Instead of welcoming our Lord’s return in 1914, her clergy got embroiled in the slaughter of World War I, in which 24 of the 28 contending nations claimed to be Christian.

21. From 1919 onward, how have Christians in the true congregation responded to Jesus’ words to the Christians in Laodicea?

²¹ Even within the true congregation, there have been lukewarm individuals who are like a drink that is neither stimulatingly hot nor refreshingly cold. But Jesus still warmly loves his congregation. He makes himself available to Christians who respond hospitably, and many have welcomed him, as though to an evening meal. As a result, from 1919 onward their eyes have been opened to the meaning of Bible prophecies. They have enjoyed a period of great enlightenment.​—Psalm 97:11; 2 Peter 1:19.
