Regarding the future of the earth and mankind...
1. On the one hand, there are those who live in FEAR: carried along even by the research of those who report that "on it's current path, human society has a shrinking window of time to alter its path", etc. (Note I'm not addressing the merit or use of the research here, but just one group's response to it).
2. On the other hand, there are those who live in DENIAL: who fail to take science as well as personal responsibilities seriously, and simply "eat, drink, and try to be merry" regardless of the consequences.
3. Then there are those who REST in God's word: which says "As long as the earth endures, seedtime and harvest, cold and heat, summer and winter, day and night will never cease." This rest involves neither neglect of wisdom nor responsibility, but results in peace even as man exercises responsibility and looks to wisdom, but trusts in the promise of God!
