I am fascinated and horrified that evangelical Christians are numbered among those who deny climate change or attribute it to non-human factors.
SIN AND THE ENVIRONMENT
The Bible declares that a high proportion of the ills besetting the environment have an origin in human sin. This is declared at the Fall (Genesis 3) and reaffirmed in places like Romans 8. Even when we do not clearly see the link, a straight-forward reading of the Bible suggests that the link is there.
Furthermore, most of the signs of the return of Christ are environmental. The sun will not really darken and the moon turn to blood. But, from an earth-bound perspective, that is how it will appear. We are all aware of how, for example, volcanic eruptions or bushfires have caused the sun and moon to appear dark, and often reddish.
Burning up of grass and drying of rivers -- these, too, are environmental disasters.
Despite the fact that human sin contributes to environmental damage, God's mandate that humans should have dominion over the creation has never been abrogated. It is just that, in our efforts, we fight an uphill battle.
GIVING THE WORLD A BREAK
There is also a clear command that the land is to have its rest -- sabbaths and jubilees -- to allow it to recover. God said (eg. Leviticus 26:34) that, when his people refuse to listen to him and remain hostile towards him, he will scatter them, lay their cities waste, and let the land have the sabbaths it has missed. This theme is also taken up in 2 Chronicles 36:21.
One evidence of this hostility is in greed: when we put money-making above God's command (as when people fail to give the land its rest) we worship mammon rather than God, because it is impossible to serve two masters.
IDOLATRY AND LAND-USE
In fact, the Bible has far less to say about abortion, homosexual activities, single-parent families and so many other bug-bears of so many conservative evangelicals than it has to say about idolatry, unjust trading, accumulation of wealth at the expense of the poor and other forms of economic and social unrighteousness. Yet we Christians far too often assume that these things are beyond God's interest!
COME OUT AND BE SEPARATE
So, when Christians fall in with the world and criticise environmental activity because of its economic costs, they fall in with the world's idolatry and mammon-worship.
I have been around long enough to remember when even non-Christians criticised Soviet-style communism for its assumption that all motivation is ultimately economic (whether or not that criticism was true is beside my point.) Since Reagan and Thatcher, the West has moved to abject mammon-worship and the assumption that economic motives dominate.
It is time for us evangelical Christians to return to our Biblical roots and stand against the world and its ways.
