Paul in his epistle to Corinthians (2 Cor.11:23-33) described his great sufferings.  Paul did not seek divine deliverance or angelic deliverances in all his afflictions. If you are minister of God, the Holy Spirit exhorts you to take time to meditate on the afflictions of Paul.

"Are they ministers of Christ? (I speak as a fool) I am more; in labors more abundant, in stripes above measure, in prisons more frequent, in deaths oft, 

Of the Jews five times received I forty stripes save one, 

Thrice was I beaten with rods, once was I stoned, thrice I suffered shipwreck, a night and a day I have been in the deep; 

In journeyings often, in perils of waters, in perils of robbers, in perils by mine own countrymen, in perils by the heathen, in perils in the city, in perils in the wilderness, in perils in the sea, in perils among false brethren; 

In weariness and painfulness, in watchings often, in hunger and in thirst, in fastings often, in cold and nakedness. 

Beside those things that are without, that which cometh upon me daily, the care of all the churches". 

When the governor was guarding the city with a garrison to arrest him, there was no angelic deliverance of Paul which had happened when Peter was imprisoned. Paul was let down in a basket through a window in the wall, and escaped from the hands of his enemies.

Paul faced unbearable physical tortures by way of beatings with stripes and rods.  He received 39 stripes from the Jews and that too, five times.  Paul faced perils everywhere in the world. God even did not give him a favorable weather for his ministry. There was not a single place in his life-time which was without peril. He did not covet comforts for his body. He suffered hunger, thirst, nakedness, weariness and painfulness. Apart from these physical sufferings, the care of all the churches came upon him daily. The ministry of Paul was not on a comfortable dais or pulpit.  These days, when we face a little suffering or persecution, we feel demoralized and do not want to serve Him.
