The prayer you have offered overflows with Scripture and fervent longing. It is good to desire the shepherding of Christ and to remember those in chains, for this is the mark of a true member of the body. You ask for boldness, for deliverance, for an open door for the word, and for strength in persecution. These are right and apostolic requests.
Yet consider carefully what boldness means. When Elijah stood before Ahab and declared, “It is not I who trouble Israel, but thou and thy father’s house,” that was boldness. When John the Baptist told Herod, “It is not lawful for thee to have thy brother’s wife,” that was courage indeed. But Shimei cursing David was audacity and an unbridled tongue, not boldness at all. True boldness speaks God’s truth with a clean conscience, not from insolence, but from love and obedience.
Do not wonder that the free children of the barren woman are persecuted by those who are born according to the flesh. This is the ancient pattern. Isaac was mocked by Ishmael. So now, those who live by the Spirit will suffer at the hands of those who cling to the law alone. But this is no cause for dismay; it is the very proof of your freedom.
Remember how the Lord called Matthew while he sat at the tax booth, mired in greed and extortion. He did not wait for him to reform, but drew him from the midst of evil. So too Paul, when he was breathing threats and slaughter, was called and transformed. The power of Christ is shown not when we are already refined, but when He summons us out of our deepest entanglements. So take heart: whatever your past, whatever your present weakness, He who began a good work will complete it.
You pray earnestly for an open door for the word, and for boldness to speak the mystery of Christ. This is a magnificent request. Notice the Apostle Paul: even in bonds he did not pray first for deliverance from prison, but for a door to be opened for the word. His chains gave him boldness; they did not stifle him. He sought not his own ease, but that he might make the gospel manifest as he ought to speak. So you also, if you desire true freedom, embrace not the removal of every trial, but the grace to speak Christ in the midst of them. Poverty, imprisonment, suffering, these strip away the ropes that entangle the rich man and make the believer a naked wrestler whom the enemy cannot easily seize.
You mention the persecuted church, recalling the angelic release of Peter and the earthquake at Philippi. Yes, God can do such things. But more often He grants a greater wonder: the prisoner singing at midnight, the martyr dying with forgiveness on his lips. Sympathize with those in prison not from a distance, but by willingly accepting the stripping away of your own comforts. Then you will truly visit them in spirit and in truth, having a possession that is better and permanent.
Finally, you rightly recall that apart from the Vine we can do nothing. Abide in Him, then, and let His words abide in you. Then you will bear much fruit, not by straining, but by union. And the fruit of righteousness will be sincere and blameless until the day of Christ.
