I’m working on my Pentecost sermon for Sunday and came across this reference to what Calvin said about this verse in his commentary on Acts. The verse says “everyone who calls on the name of the Lord shall be saved.”

Therefore, howsoever man be swallowed up ill the gulf of miseries, yet is there set before him a way to escape. We must also note the universal word, whosoever For God admitteth all men unto himself without exception, and by this means doth he invite them to salvation, as Paul gathereth in the tenth chapter to the Romans, and as the prophet had set it down before,

“Thou, Lord, which hearest the prayer,
unto thee shall all flesh come,”
(Psalm 65:2.)

Therefore, forasmuch as no man is excluded from calling upon God, the gate of salvation is set open unto all men; neither is there any other thing which keepeth us back from entering in, save only our own unbelief. I speak of all unto whom God doth make himself manifest by the gospel.

That is what Calvin wrote.  pvk
