All that the Father gives Me will come to Me, and the one who comes to Me I will by no means cast out. For I have come down from heaven, not to do My own will, but the will of Him who sent Me. This is the will of the Father who sent Me, that of all He has given Me I should lose nothing, but should raise it up at the last day...No man can come to me, except the Father which hath sent me draw him, and I will raise him up at the last day.
John 6:37-39 and 44
