Jesus' priestly heart is revealed in the prayer of John 17. Verses 17-19 say: 'Sanctify them through thy truth: thy word is truth. As thou hast sent me into the world, even so have I also sent them into the world. And for their sakes, I sanctify myself, that they also might be sanctified through the truth.' Jesus goes on to pray, not for the world, but for those who were given to him, and they that would believe because of them. He set Himself apart (sanctified) that all who believed in Him would also be set apart... from a world system that refuses Him. I find so much fellowship in this, and comfort knowing that truth has the effect of setting us apart. Jesus is that truth.
