All of us who have believed in Christ, like the patriarchs, are "looking for the city which has foundations, whose architect and builder is God" (Heb. 11:10, NASB).
Believers of old were "seeking a country of their own" (v. 14, NASB), and we, too, are seeking a heavenly country. Even though we reside on earth, our legal residence is in heaven.
Therefore, our minds should be on that which originates in heaven rather than on that which originates on earth.
Paul told of those whose minds were on earthly things. He referred to them as "enemies of the cross of Christ, whose end is destruction, whose god is their appetite, and whose glory is in their shame, who set their minds on earthly things" (Phil. 3:18,19, NASB).
In contrast to this kind of people, the believer is to follow the injunctions of Colossians 3:1-3: "If then you have been raised up with Christ, keep seeking the things above, where Christ is, seated at the right hand of God. Set your mind on the things above, not on the things that are on earth. For you have died and your life is hidden with Christ in God" (NASB).
Jesus Himself prayed, "Thy will be done in earth, as it is in heaven" (Matt. 6:10). Jesus was concerned about God's will being carried out, not just in the end times but also now in the believer.
So whereas the pattern of our life is heavenly, the practice is here on earth.
"And now, little children, abide in him; that, when he shall appear, we may have confidence, and not be ashamed before him at his coming" (1 John 2:28).
