The phrase "an acceptable time" signifies a period chosen by God based on His own good pleasure and grace. Commentators like John Calvin and Albert Barnes explain this isn't a random moment, but the specific, divinely appointed era for salvation through the Messiah. Citing the Apostle Paul (2 Cor. 6:2), they affirm that this "day of salvation" is now, the time when the gospel is preached and God's favor is extended to all.
