15In those days Peter stood up among the believers (together the crowd numbered about one hundred twenty persons) and said, 16“Friends, the scripture had to be fulfilled, which the Holy Spirit through David foretold concerning Judas, who became a guide for those who arrested Jesus—17for he was numbered among us and was allotted his share in this ministry.” 18(Now this man acquired a field with the reward of his wickedness; and falling headlong, he burst open in the middle and all his bowels gushed out. 19This became known to all the residents of Jerusalem, so that the field was called in their language Hakeldama, that is, Field of Blood.) 20“For it is written in the book of Psalms, ‘Let his homestead become desolate, and let there be no one to live in it’; and ‘Let another take his position of overseer.’ (Acts 1:15-20, NRSV)
What does the Hebrew Scripture say about Judas, well there is some debate about that. Some say that Psalm 69:25 (May their camp be a desolation; let no one live in their tents.) is about David, but has further Messianic application. That this applies to Judas that none should live where he was. But this is not always agreed upon. And thus prolongs the problem of Judas being a necessary evil, and not a person doing his best for Jesus and what he thought God was leading him to.
So how do we not fall into the trap of being a Judas, and being dispised for doing what we feel God is leading us to do?
12Then they returned to Jerusalem from the mount called Olivet, which is near Jerusalem, a sabbath day’s journey away. 13When they had entered the city, they went to the room upstairs where they were staying, Peter, and John, and James, and Andrew, Philip and Thomas, Bartholomew and Matthew, James son of Alphaeus, and Simon the Zealot, and Judas son of James. 14All these were constantly devoting themselves to prayer, together with certain women, including Mary the mother of Jesus, as well as his brothers. (Acts 1:12-14, NRSV)
6So when they had come together, they asked him, “Lord, is this the time when you will restore the kingdom to Israel?” 7He replied, “It is not for you to know the times or periods that the Father has set by his own authority. 8But you will receive power when the Holy Spirit has come upon you; and you will be my witnesses in Jerusalem, in all Judea and Samaria, and to the ends of the earth.” 9When he had said this, as they were watching, he was lifted up, and a cloud took him out of their sight.10While he was going and they were gazing up toward heaven, suddenly two men in white robes stood by them. 11They said, “Men of Galilee, why do you stand looking up toward heaven? This Jesus, who has been taken up from you into heaven, will come in the same way as you saw him go into heaven.” (Acts 1:6-11, NRSV)
16Now the eleven disciples went to Galilee, to the mountain to which Jesus had directed them. 17When they saw him, they worshiped him; but some doubted. 18And Jesus came and said to them, “All authority in heaven and on earth has been given to me. 19Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, 20and teaching them to obey everything that I have commanded you. And remember, I am with you always, to the end of the age.” (Matthew 28:16-20, NRSV)
15When they had finished breakfast, Jesus said to Simon Peter, “Simon son of John, do you love me more than these?” He said to him, “Yes, Lord; you know that I love you.” Jesus said to him, “Feed my lambs.” 16A second time he said to him, “Simon son of John, do you love me?” He said to him, “Yes, Lord; you know that I love you.” Jesus said to him, “Tend my sheep.” 17He said to him the third time, “Simon son of John, do you love me?” Peter felt hurt because he said to him the third time, “Do you love me?” And he said to him, “Lord, you know everything; you know that I love you.” Jesus said to him, “Feed my sheep. 18Very truly, I tell you, when you were younger, you used to fasten your own belt and to go wherever you wished. But when you grow old, you will stretch out your hands, and someone else will fasten a belt around you and take you where you do not wish to go.” 19(He said this to indicate the kind of death by which he would glorify God.) After this he said to him, “Follow me.” 20Peter turned and saw the disciple whom Jesus loved following them; he was the one who had reclined next to Jesus at the supper and had said, “Lord, who is it that is going to betray you?” 21When Peter saw him, he said to Jesus, “Lord, what about him?” 22Jesus said to him, “If it is my will that he remain until I come, what is that to you? Follow me!” 23So the rumor spread in the community that this disciple would not die. Yet Jesus did not say to him that he would not die, but, “If it is my will that he remain until I come, what is that to you?” 24This is the disciple who is testifying to these things and has written them, and we know that his testimony is true. 25But there are also many other things that Jesus did; if every one of them were written down, I suppose that the world itself could not contain the books that would be written. (John 21:15-25, NRSV)
