Whoever calls on the name of the Lord shall be saved.

But Peter, standing up with the eleven, raised his voice and said to them, “Men of Judea and all who dwell in Jerusalem, let this be known to you, and heed my words. For these are not drunk, as you suppose, since it is only  the third hour of the day. But this is what was spoken by the prophet Joel: ‘And  it shall come to pass in the last days, says God, That I will pour out of My Spirit on all flesh; Your sons and  your daughters shall prophesy, Your young men shall see visions, Your old men shall dream dreams. And on My menservants and on My maidservants I will pour out My Spirit in those days; And they shall prophesy. I will show wonders in heaven above And signs in the earth beneath: Blood and fire and vapor of smoke. The sun shall be turned into darkness, And the moon into blood, Before the coming of the great and awesome day of the  Lord. And it shall come to pass That  whoever calls on the name of the  Lord Shall be saved.’ “Men of Israel, hear these words: Jesus of Nazareth, a Man attested by God to you by miracles, wonders, and signs which God did through Him in your midst, as you yourselves also know— Him, being delivered by the determined purpose and foreknowledge of God, you have taken by lawless hands, have crucified, and put to death; whom God raised up, having loosed the pains of death, because it was not possible that He should be held by it.  Acts 2:14-24 - NKJV
