Luke 18:7-8 (KJV)
7 And shall not God avenge his own elect, which cry day and night unto him, though he bear long with them?
8 I tell you that he will avenge them speedily. Nevertheless when the Son of man cometh, shall he find faith on the earth?
Luke 7:20-23 (NLT)
20 John’s two disciples found Jesus and said to him, “John the Baptist sent us to ask, ‘Are you the Messiah we’ve been expecting, or should we keep looking for someone else?’”
21 At that very time, Jesus cured many people of their diseases, illnesses, and evil spirits, and he restored sight to many who were blind. 22 Then he told John’s disciples, “Go back to John and tell him what you have seen and heard—the blind see, the lame walk, the lepers are cured, the deaf hear, the dead are raised to life, and the Good News is being preached to the poor. 23 And tell him, ‘God blesses those who do not turn away because of me

Mark 16:14-20 (NLT)
14 Still later he appeared to the eleven disciples as they were eating together. He rebuked them for their stubborn unbelief because they refused to believe those who had seen him after he had been raised from the dead.
15 And then he told them, “Go into all the world and preach the Good News to everyone. 16 Anyone who believes and is baptized will be saved. But anyone who refuses to believe will be condemned. 17 These miraculous signs will accompany those who believe: They will cast out demons in my name, and they will speak in new languages.
18 They will be able to handle snakes with safety, and if they drink anything poisonous, it won’t hurt them. They will be able to place their hands on the sick, and they will be healed.”
19 When the Lord Jesus had finished talking with them, he was taken up into heaven and sat down in the place of honor at God’s right hand. 20 And the disciples went everywhere and preached, and the Lord worked through them, confirming what they said by many miraculous signs.
