Acts 20 contains the story of young Eutychus falling from the window during one of the apostle's long sermons. Luke mentions the lamps probably because they contributed to the subsequent event. A large number of lamps had likely been lighted so that all the brethren could see Paul and perhaps take notes on his teaching. However, lamps not only emit a great deal of light, but they also put off a lot of heat, so Luke almost certainly intends the reader to understand that the audience was becoming a little drowsy due to both the warmth and the late hour.
Luke's verbiage is matter-of-fact and unemotional. The apostle remains calm and collected throughout the incident. He does not race down the stairs, fly into hysterics, or wail about how tragically this young man's life ended. Even the English expression of his "falling on" Eutychus is a bit overdone since the Greek word, epipipto, has the sense here of pressing or lying upon. In other words, the apostle stretches himself out on Eutychus as Elisha did with the Shunammite's son (II Kings 4:34-35), then he coolly tells everyone not to worry, for the young man would live. Before long, the brethren are eating a meal together (verse 11)!
Paul does not react to Eutychus' death with the proverbial weeping and gnashing of teeth. By his placid demeanor, he reassures the brethren and proceeds to exhibit God's power and mercy. Remaining so composed in such a situation may seem almost inhuman to be able to do. We humans are usually so full of emotion for our loved ones that we become absolutely distraught when a death occurs, but these examples from Scripture show that, while grief is normal, a hopeful, positive expectation of life to come is a more spiritually mature attitude toward death.
The faith of Jesus and Paul allowed them to consider death almost from a detached point of view. Certainly, they felt the same emotions as we do, but they suppressed them to a large degree, not because they were callous, but because their hope in what God offers beyond death far exceeded them. To them, death was not the end but a necessary step toward a better life. Jesus Christ, "who for the joy that was set before Him endured the cross, despising the shame, and has sat down at the right hand of the throne of God" (Hebrews 12:2). And for his part, Paul writes in Romans 8:18, "For I consider that the sufferings of this present time are not worthy to be compared with the glory which shall be revealed in us."
How could they do this? They knew what death really is, and along with their deep faith in God's plan, power, and promises, they could face it with unwavering hope.
