Heavenly Focus

Since then, you have been raised with Christ,

set your hearts on things above,

where Christ is, seated at the right hand of God.

Colossians 3.1

Your kingdom come, your will be done, on earth as it is in heaven.

Matthew 6:10

Mark Meynell:

In other words, as the kingdom extends in the here and now in space and time, the beauty and values of heaven become more visible and tangible on earth. A heavenly focus produces an earthly difference. In fact, it should make all the difference in the world. 

C.S. Lewis understood this perfectly. The Bible is not advocating a form of escapism or wishful thinking:

It does not mean that we are to leave the present world as it is. If you read history you will find that the Christians who did most for the present world were just those who thought most of the next. The Apostles themselves, who set on foot the conversion of the Roman Empire, the great men who built up the Middle Ages, the English Evangelicals who abolished the Slave Trade, all left their mark on Earth, precisely because their minds were occupied with Heaven. It is since Christians have largely ceased to think of the other world that they have become so ineffective in this. Aim at Heaven and you will get earth ‘thrown in’: aim at earth and you will get neither.
