For too long, evangelical Christians have neglected our God-given calling to care for the planet entrusted to us. One reason may be that our eschatology indicates the earth is headed for ruin anyway, so there’s no point in trying to rearrange the furniture on the Titanic.

Randy Alcorn talks about how the New Earth will be the old earth, made new.

Some Bible teachers think that the Earth will be completely destroyed and a different earth will be made from scratch.

When we die we go to be with Christ (II Cor. 5:8) which is wonderful. But we are still incomplete, in a pre-resurrected state, anticipating Christ's return to earth, and our resurrections. The place we'll live forever will be where God comes down to dwell with us, on the New Earth (Revelation 21:1-3).
