Sometime in the latter AD ’60s, Paul, the apostle looked out of the tiny grate that let in light to his subterranean dungeon. The Mamertine prison was only a stone’s throw from the epicenter of the world, the Roman Forum.
Outside could be heard the crowds surging to the Circus Maximus, the games and the great festivals. The mighty
legions returned from victory after victory with dazzling displays of plunder and captives.
And there ten feet under the streets of ancient Rome in a damp, dirty hole in the ground, in that solitary dungeon of deprivation and discomfort, once again the Holy Spirit of God overshadowed the great apostle and began to breathe through him the very Word of God. As the victorious armies streamed into the Eternal City they had to pass within yards of that iron-barred dungeon. If a legionnaire had bothered to take a moment to look down that hole, he might have seen a faint glow of a candle as a worn-out old man, bound with chains, hunched over a scroll and laboriously wrote some words to an old friend.
So, in the late Autumn of life sits the Apostle who dominates the early years of the church. Here awaiting execution in this most undesirable spot, is Saint Paul. Look at his last words from this very spot… 2 Timothy 4:6 For I am already being poured out (spendomai) as a drink offering (an Old Testament sacrifice of thanks to God), and the time of my departure is at hand. What is this? It is the voice of the “The Apostle of Thanks”
As God’s missionary Paul wrote a travel diary – let me read it to you: 2 Cor. 11. “But whatever anyone dares to boast of…I also dare to boast of that…Are they servants of Christ? I am a better one–I am talking like a madman–with far greater labors, far more imprisonments, with countless beatings, and often near death. Five times I have received at the hands of the Jews the forty lashes less one. Three times I have been beaten with rods; once I was stoned. Three times I have been shipwrecked; a night and a day I have been adrift at sea; on frequent journeys, in danger from rivers, danger from robbers, danger from my own people, danger from Gentiles, danger in the city, danger in the wilderness, danger at sea, danger from false brethren; in toil and hardship, through many a sleepless night, in hunger and thirst, often without food, in cold and exposure. And, apart from other things, there is the daily pressure upon me of my anxiety for all the churches.” Most of those events are not in Acts so this is such an intimate look!
Add to this the constant walks up and down those Roman roads and all that it entailed of over 1200 WALKING miles.
 Paul endured every form of hardship, encountering every extremity of danger (2 Cor. 11:23-27).
 Paul was attacked by angry townspeople, punished by cruel magistrates (Acts 16:19-24; 21:27).
 Paul was scourged, beaten, stoned, left for dead (Acts 14:19-20).
 Paul could only expect more of the same treatment and the same dangers (Acts 20:23).
 Paul was driven from one city, so he just went on to preach in the next (Acts 13:50-51; 14:5-7,19-21).
 Paul invested his whole life in missionary work, sacrificing to the Lord all of his personal time for pleasures, ease, and security (Acts 20:24; Rom. 1:14-15; Phil. 1:20; 3:8).
 Paul chose to keep on this course to old age, unaltered by the experience of hardness (Acts 28:17); thankless Christians (Gal. 1:6; 4:14-20); unjustified prejudice (II Cor. 12:15); and even desertion by his closest friends (11 Tim. 4:10, 16).
