Mark 1:38

And he said unto them, I must preach the kingdom of God to other cities also: for therefore am I sent.

For I have given unto them the words which thou gavest me; and they have received them, and have known surely that I came out from thee, and they have believed that thou didst send me.

I have glorified thee on the earth: I have finished the work which thou gavest me to do.

And he said unto them, How is it that ye sought me? wist ye not that I must be about my Father’s business?

I came forth from the Father, and am come into the world: again, I leave the world, and go to the Father.

I must work the works of him that sent me, while it is day: the night cometh, when no man can work.
