A better objective would be to follow another statement made not by a committee but by a single individual who claims ownership of His church and requires obedience to all who would follow Him: "Go and make disciples of all nations." (Matthew 28:19) Jesus also called on His disciples - then and now - "to obey everything I have commanded you." A quick look does not reveal those teachings as having anything to do with global warming or the environment. Rather, He calls individuals to feed the hungry, clothe the naked, visit those in prison and pray for those who persecute them. Evangelicals should pursue these higher virtues instead of settling for the lower life of politics.
John the Apostle warns, "Do not love the world or anything in the world. ... The world and its desires pass away, but the man who does the will of God lives forever." (1 John 2:15,17)
Some evangelicals lift a verse from Genesis that speaks of being good stewards and "taking care" of the earth. But that was before the fall of man, when sin and corruption entered the world.
I'm all for trying to keep the air and water as clean as possible, and I do not toss litter on the ground, but I worry that, having been mugged several times before at the end of the political alley, evangelicals may be setting themselves up for more damage to their credibility.
The environmental models pertaining to planet temperatures have not been studied long enough to reach such a profound conclusion that unless Americans drive different cars, the planet will burn up due to carbon monoxide gas. It is more likely to burn up due to nuclear weapons in the hands of nuts like the president of Iran.
If evangelicals make the environment another "cause," they are likely to be as frustrated and disappointed as when they exercised misplaced faith in politics to cure other social evils. Should they desire a real effect on the planet, let them return to the eternal message that has been given them to share with a world that needs it now more than ever. That is a message which "cleans up" the inside of the hearts of men and women and places them in a position to more powerfully influence this world and prepare themselves and others for the world to come.
