““Yet even now,” declares the Lord,
“return to me with all your heart,
with fasting, with weeping, and with mourning;
and rend your hearts and not your garments.”
Return to the Lord your God,
for he is gracious and merciful,
slow to anger, and abounding in steadfast love;
and he relents over disaster.
Who knows whether he will not turn and relent,
and leave a blessing behind him,
a grain offering and a drink offering
for the Lord your God? Blow the trumpet in Zion;
consecrate a fast;
call a solemn assembly; gather the people.
Consecrate the congregation;
assemble the elders;
gather the children,
even nursing infants.
Let the bridegroom leave his room,
and the bride her chamber. Between the vestibule and the altar
let the priests, the ministers of the Lord, weep
and say, “Spare your people, O Lord,
and make not your heritage a reproach,
a byword among the nations. Why should they say among the peoples,
‘Where is their God?’”
Joel 2:12-17
[7] He said to them, “It is not for you to know times or seasons that the Father has fixed by his own authority. [8] But you will receive power when the Holy Spirit has come upon you, and you will be my witnesses in Jerusalem and in all Judea and Samaria, and to the end of the earth.”
[9] Therefore God has highly exalted him and bestowed on him the name that is above every name, [10] so that at the name of Jesus every knee should bow, in heaven and on earth and under the earth
[19] On the evening of that day, the first day of the week, the doors being locked where the disciples were for fear of the Jews, Jesus came and stood among them and said to them, “Peace be with you.” [20] When he had said this, he showed them his hands and his side. Then the disciples were glad when they saw the Lord. [21] Jesus said to them again, “Peace be with you. As the Father has sent me, even so I am sending you.” [22] And when he had said this, he breathed on them and said to them, “Receive the Holy Spirit. [23] If you forgive the sins of any, they are forgiven them; if you withhold forgiveness from any, it is withheld.”
Luke 24:44-49
[44] Then he said to them, “These are my words that I spoke to you while I was still with you, that everything written about me in the Law of Moses and the Prophets and the Psalms must be fulfilled.” [45] Then he opened their minds to understand the Scriptures, [46] and said to them, “Thus it is written, that the Christ should suffer and on the third day rise from the dead, [47] and that repentance for[a] the forgiveness of sins should be proclaimed in his name to all nations, beginning from Jerusalem. [48] You are witnesses of these things. [49] And behold, I am sending the promise of my Father upon you. But stay in the city until you are clothed with power from on high.”
