Matthew 9:35-38 (ESV)
35 And Jesus went throughout all the cities and villages, teaching in their synagogues and proclaiming the gospel of the kingdom and healing every disease and every affliction.
36 When he saw the crowds, he had compassion for them, because they were harassed and helpless, like sheep without a shepherd.
37 Then he said to his disciples, “The harvest is plentiful, but the laborers are few;
38 therefore pray earnestly to the Lord of the harvest to send out laborers into his harvest.”
Matthew 16:21-28 (ESV)
21 From that time Jesus began to show his disciples that he must go to Jerusalem and suffer many things from the elders and chief priests and scribes, and be killed, and on the third day be raised.
22 And Peter took him aside and began to rebuke him, saying, “Far be it from you, Lord! This shall never happen to you.”
23 But he turned and said to Peter, “Get behind me, Satan! You are a hindrance to me. For you are not setting your mind on the things of God, but on the things of man.”
24 Then Jesus told his disciples, “If anyone would come after me, let him deny himself and take up his cross and follow me.
25 For whoever would save his life will lose it, but whoever loses his life for my sake will find it.
26 For what will it profit a man if he gains the whole world and forfeits his soul? Or what shall a man give in return for his soul?
27 For the Son of Man is going to come with his angels in the glory of his Father, and then he will repay each person according to what he has done.
28 Truly, I say to you, there are some standing here who will not taste death until they see the Son of Man coming in his kingdom.”
Matthew 28:19 (ESV)
19 Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit,
