Devote yourselves to prayer, keeping alert in it with an attitude of thanksgiving; praying at the same time for us as well, that God will open up to us a door for the word, so that we may speak forth the mystery of Christ, for which I have also been imprisoned; that I may make it clear in the way I ought to speak.
Similarly, Acts 14:1 states: “In Iconium they entered the synagogue of the Jews together, and spoke in such a manner that a large number of people believed, both of Jews and of Greeks.”
Paul didn’t ask to pray that a door be opened so that he could escape prison. God had opened that door many times already. Instead, Paul was more interested in a door being opened so that lost sinners could escape. But if Calvinism is true, would anyone additional be saved if everyone prayed? Would any less be saved, if no one prayed? Calvinism contends that the number of the elect is fixed, predetermined and cannot change, which makes the necessity of these things perplexing. However, the Calvinist answer is that we are commanded to evangelize. But that doesn’t answer the question of Paul’s fervency for when he went above and beyond the call of duty. For that, Calvinists have a different answer, and that is the “predestined means.” When backed into a corner, that’s where Calvinists will turn. Calvinists can simply pull out that argument, and no additional thought is required: It’s just the predestined means!
