Matthew 4:18-22 (KJV)
18 And Jesus, walking by the sea of Galilee, saw two brethren, Simon called Peter, and Andrew his brother, casting a net into the sea: for they were fishers. 19 And he saith unto them, Follow me, and I will make you fishers of men. 20 And they straightway left their nets, and followed him. 21 And going on from thence, he saw other two brethren, James the son of Zebedee, and John his brother, in a ship with Zebedee their father, mending their nets; and he called them. 22 And they immediately left the ship and their father, and followed him.
Luke 9:57-62 (KJV)
57 And it came to pass, that, as they went in the way, a certain man said unto him, Lord, I will follow thee whithersoever thou goest. 58 And Jesus said unto him, Foxes have holes, and birds of the air have nests; but the Son of man hath not where to lay his head. 59 And he said unto another, Follow me. But he said, Lord, suffer me first to go and bury my father. 60 Jesus said unto him, Let the dead bury their dead: but go thou and preach the kingdom of God. 61 And another also said, Lord, I will follow thee; but let me first go bid them farewell, which are at home at my house. 62 And Jesus said unto him, No man, having put his hand to the plough, and looking back, is fit for the kingdom of God.
Luke 10:2 (KJV)
2 Therefore said he unto them, The harvest truly is great, but the labourers are few: pray ye therefore the Lord of the harvest, that he would send forth labourers into his harvest.
1 Corinthians 3:6-9 (KJV)
6 I have planted, Apollos watered; but God gave the increase. 7 So then neither is he that planteth any thing, neither he that watereth; but God that giveth the increase. 8 Now he that planteth and he that watereth are one: and every man shall receive his own reward according to his own labour. 9 For we are labourers together with God: ye are God’s husbandry, ye are God’s building.
