KEY TEXT: Isaiah 51:6 Lift up your eyes to the heavens, look at the earth beneath; the heavens will vanish like smoke, the earth will wear out like a garment and its inhabitants die like flies. But my salvation will last forever, my righteousness will never fail. (NIV)
KEY THOT: Everything we can see with our eyes will one day disappear. The heavens will "vanish like smoke", the earth will "wear out like a garments" and even peoples on earth will "die like flies" (v.6). Nothing we can see with our eyes will last. But the invisible--God's salvation and righteousness--will last forever. The visible things are all temporal and temporary; but the invisible things (God's kingdom and righteousness) are eternal. If our goal in life is to acquire material goods, then we are chasing after the wind. But if our goal in life is to invest in eternal realities, then we are building an inheritance that will never fail: "my salvation will last forever" (v.6).
Paul in 2 Corinthians 4:17-18 affirms the same truth: "For this slight momentary affliction is preparing for us an eternal weight of glory beyond all comparison, as we look not to the things that are seen but to the things that are unseen. For the things that are seen are transient, but the things that are unseen are eternal." So, what are we "eyeing" in this life? The latest smartphone? The state of art electronic gadget? The branded handbags? These visible things will perish. If we are preoccupied only in pursuing these visible goods, then we are foolish, for we cannot take any of these with us when we die. Only the invisible kingdom of God and His righteousness are eternal. Only these invisible things are worth dying for. Jesus says our life focus reveals also the spiritual condition of our heart: "Do not lay up for yourselves treasures on earth, where moth and rust destroy and where thieves break in and steal, but lay up for yourselves treasures in heaven, where neither moth nor rust destroys and where thieves do not break in and steal. For where your treasure is, there your heart will be also" (Matthew 6:19-21).
Basically, Jesus is saying that your heart will follow your treasures. If we focus on visible things, our hearts will soon be found there. But if we focus on invisible realities (God's salvation and righteousness) then our hearts will become Christ-centred, for it be found among these eternal treasures.
Abba-Father, thank You for the eternal salvation You have granted us that will last forever. Everything visible in this life is temporal. Help us to invest our lives in things that are eternal. Amen.
