Joel 2:32
30 I will produce portents both in the sky and on the earth—blood, fire, and columns of smoke. 31 The sunlight will be turned to darkness and the moon to the color of blood, before the day of the Lord comes—that great and terrible day! 32 It will so happen that everyone who calls on the name of the Lord will be delivered. For on Mount Zion and in Jerusalem there will be those who survive, just as the Lord has promised; the remnant will be those whom the Lord will call.
Romans 10:13
12 For there is no distinction between the Jew and the Greek, for the same Lord is Lord of all, who richly blesses all who call on him. 13 For everyone who calls on the name of the Lord will be saved. 14 How are they to call on one they have not believed in? And how are they to believe in one they have not heard of? And how are they to hear without someone preaching to them?
Notes and References
"... The earliest reuse of Joel appears in the New Testament. Romans 10:13 and 1 Corinthians 1:2 use unmarked citations of Joel 3:5a [2:32] to buttress a claim that salvation is universally available, while Acts 10:45 and Titus 3:6 allude to Joel 3:1 in referring to Pentecost a precursor of the gift of the Spirit to Gentiles. Beyond these, some dystopian eschatological scenarios utilize Joel’s descriptions of harvest (Mark 4:29 / Joel 4:13a), the darkening of sun, moon and stars (Mark 13:24 / Matt 24:29 / Joel 2:10), the moon turning to blood (Revelation 6:12 / Joel 2:10; 3:4), and the plague of locusts (Revelation 9:7–9 / Joel 2:4–5b) ..."
