Luke 10:2
2 These were his instructions to them: “The harvest is great, but the workers are few. So pray to the Lord who is in charge of the harvest; ask him to send more workers into his fields.

Matthew 20:24–28
24 When the ten other disciples heard what James and John had asked, they were indignant. 25 But Jesus called them together and said, “You know that the rulers in this world lord it over their people, and officials flaunt their authority over those under them. 26 But among you it will be different. Whoever wants to be a leader among you must be your servant, 27 and whoever wants to be first among you must become your slave. 28 For even the Son of Man came not to be served but to serve others and to give his life as a ransom for many.”

Ephesians 2:8–10
8 God saved you by his grace when you believed. And you can’t take credit for this; it is a gift from God. 9 Salvation is not a reward for the good things we have done, so none of us can boast about it. 10 For we are God’s masterpiece. He has created us anew in Christ Jesus, so we can do the good things he planned for us long ago.
