Recently we were reading Matt 6.19-21 in our devotions. I was especially challenged by our Lord's words in verse 21: 'For where your treasure is, there your heart will be also'. The cosmic perspective into which this passage fits is the heaven-and-earth milieu (that dominates all of holy Scripture). Jesus' teaching challenges his hearers to assess their attitudes and heart-commitments in the light of heaven.
we look not to the things that are seen but to the things that are unseen --Paul, Apostle to the Gentiles
