John Calvin on Eschatological Pilgrims

Let us always look at our Lord Jesus Christ. And for as much as we know that God's Son is come down hither, and will hereafter receive us into his glory, yea, and that God hath made him head of the angels as well as of us: let us assume ourselves that although we be here in this world, yet notwithstanding, we be but as pilgrims and cease not for all that to be citizens of heaven whereunto we be led by hope. And for the same cause he saith in another place that we be set already in the heavenly places. And how? By hope.
