John 6:37-39

37All that the Father gives me shall come to me, and him that comes to me I will not at all cast out.

38For I am come down from heaven, not that I should do my will, but the will of him that has sent me.

39And this is the will of him that has sent me, that of all that he has given me I should lose nothing, but should raise it up in the last day.
