Since the Industrial Revolution in the early 1700s, mankind has been using coal, oil, and natural gas for energy. These fossil fuels are depleted from the earth each year; they aren’t renewable. Like wind and hydroelectric power, solar energy is renewable. However, using it to power homes and businesses on a national scale is still an economic and scientific problem.
“The first man was of the earth, made of dust. The second man is the Lord from heaven. As was the man of dust, so also are those who are made of dust. And as is the heavenly Man, so also are those who are heavenly. As we have borne the image of the man of dust, we shall also bear the image of the heavenly Man.” – 1 Corinthians 15:47-49
This contrast between fossil fuels and solar energy is a perfect portrait of the spiritual state of people today. Sinners seek spiritual energy from earthly things – wealth, power, fame, substance abuse, etc. But they aren’t renewable sources. One day, the tap will run dry and the toil is exhausting. Christians, however, seek spiritual energy from Jesus Christ, “the Sun of Righteousness … with healing in his wings” (Malachi 4:2). Jesus’ disciples stayed in Jerusalem until they were “endued with power from on high” – the Holy Spirit (Luke 24:49). This energy source is everlasting and we don’t have to do anything except soak up the sun. Jesus tells us not to worry about our lives, since “the birds of the air … neither sow nor reap nor gather into barns” and “the lilies of the field … neither toil nor spin” (Matthew 6:25-26, 28).
Do we daily run on the renewable juice of the Holy Spirit or on earthly things that won’t last? The choice is ours, but its consequences are eternal. Unconverted people who retain the image of the first Adam will enter hell. Those who have been converted and transformed by the Spirit into the image of the last Adam, Jesus Christ, will enter heaven (2 Corinthians 3:18). Therefore, let us give up spiritual fossil fuels and embrace the Sun of Righteousness, the ever-living Jesus Christ. He is the same – yesterday, today, and forever (Hebrews 13:8).
