His.

I have revealed you to those whom you gave me out of the world. They were yours; you gave them to me and they have obeyed your word. Now they know that everything you have given me comes from you. For I gave them the words you gave me and they accepted them. They knew with certainty that I came from you, and they believed that you sent me. I pray for them. I am not praying for the world, but for those you have given me, for they are yours. (John 17:6-9)
