Acts 27:21-26 (see also Jeremiah 38:17-23)
When they had gone a long time without food, then Paul stood up in their midst and said, “Men, you ought to have followed my advice and not to have set sail from Crete and incurred this damage and loss. Yet now I urge you to keep up your courage, for there will be no loss of life among you, but only of the ship. For this very night an angel of the God to whom I belong and whom I serve stood before me, saying, ‘Do not be afraid, Paul; you must stand before Caesar; and behold, God has granted you all those who are sailing with you.’ Therefore, keep up your courage, men, for I believe God that it will turn out exactly as I have been told. ‘But we must run aground on a certain island.’”
If Paul believed in Determinism, then what would be the point of telling them what they “ought” to have done, as if to shame them? If he believed in Determinism, their actions would be scripted, regardless. “Shame on you for doing what you were inalterably scripted to do!” Does that make sense?
First of all, if all of Zedekiah’s actions were predetermined by God, then Jeremiah was the last to know. For he seems to think that Zedekiah had the power of contrary choice, since before him, were two possible futures, and the Lord had shown Jeremiah both, and that’s why he was pleading so hard with Zedekiah not to take the foolish route. Therefore, applying this principle to Acts chapter 27, had Paul kept silent, those men would have perished. Additionally, had those men not listened to Paul, they would have perished. Just like with Jeremiah chapter 38, there were two possible outcomes, and Paul relayed the one in which he was granted no loss of life. Similarly with Jeremiah chapter 38, Jeremiah relayed the outcome in which what? In which it would have “gone well” with Zedekiah, but he refused. This is why Calvinists are in error of their understanding of Acts chapter 27. These simply took the opposite route of Zedekiah.
Consider other examples of God granting something:
Acts 5:31: “He is the one whom God exalted to His right hand as a Prince and a Savior, to grant repentance to Israel, and forgiveness of sins.”
Acts 11:18: “When they heard this, they quieted down and glorified God, saying, ‘Well then, God has granted to the Gentiles also the repentance that leads to life.’”
God has granted repentance to both Israel and the Gentiles. In fact, Acts 26:20 states: “...but kept declaring both to those of Damascus first, and also at Jerusalem and then throughout all the region of Judea, and even to the Gentiles, that they should repent and turn to God, performing deeds appropriate to repentance.” So everyone has been granted repentance, that is, the opportunity to actually do so, and have it received by God. God has essentially opened the door for their salvation. John 3:16 easily fits within this, because with their opportunity, still comes their obligation to act upon the opportunity, which is to repent, believe and become saved, and thus to receive the gift of eternal life. So in terms of the sailors, God granted Paul their lives, but implicit to that promise was a condition which Paul specifically warned about. So there really is no evidence of Determinism here. Calvinists simply manufacture it.
