Jn 6:39-40, 1 Jn 5:1, Jn 20:31, Mt 28:19-20, Mk 16:15, Acts 1:8

In the parable of the steward, Jesus said that the servant who knows the master's will but does not do it will be beaten a lot. (Lk 12:47-48)

Lk 12:47 And that servant, which knew his lord's will, and prepared not himself, neither did according to his will, shall be beaten with many stripes. 48 But he that knew not, and did commit things worthy of stripes, shall be beaten with few stripes. For unto whomsoever much is given, of him shall be much required: and to whom men have committed much, of him they will ask the more.

Then, what is the will of the master, the will of God? It is believing in One whom God has sent. God's will is to believe in Jesus as the Christ. (Jn 6:39-40, 1 Jn 5:1, Jn 20:31)

Jn 6:39 And this is the Father's will which hath sent me, that of all which he hath given me I should lose nothing, but should raise it up again at the last day. 40 And this is the will of him that sent me, that every one which seeth the Son, and believeth on him, may have everlasting life: and I will raise him up at the last day.

1 Jn 5:1 Whosoever believeth that Jesus is the Christ is born of God: and every one that loveth him that begat loveth him also that is begotten of him.

Jn 20:31 But these are written, that ye might believe that Jesus is the Christ, the Son of God; and that believing ye might have life through his name.

And to spread this gospel to the whole world. (Mt 28:19-20, Mk 16:15, Acts 1:8)

Mt 28:19 Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost:

20 Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you always, even unto the end of the world. Amen.

Mk 16:15 And he said unto them, Go ye into all the world, and preach the gospel to every creature.

Acts 1:8 But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth.
