As the old spiritual goes - -This world is not my home, I'm just a passin' through.- Paul puts it this way - -our citizenship is in heaven.- This truth determines both our hope of glory to come as we await a Saviour from heaven - Jesus Christ, and how we live in this world today - not with our minds set on earthly things but on Christ and the kingdom of God. Knowing where we are heading and truly belong enables us to -stand firm in the Lord- when sin and worldly pressures would have us do otherwise.
