consider the following verses:
Psalm 24:1 The earth is the LORD's, and everything in it,
the world, and all who live in it;
Genesis 2:15 - The LORD God took the man and put him in the Garden of Eden to work it and take care of it.True environmental care is respect for God's handiwork, not a return to idolatry. Stewardship is the recognition of humanity's high created position, not a pantheistic ruling out of our responsibility before God.
Environmental issues are a major concern of our day. Christians should do their part to help the earth glorify God. After all, we know the Creator. Of course, we must also spread the gospel message, telling others about the Creator of heaven and earth.
Perhaps the confusion is that if in any case Pre-Tribulational, Pre-Millenial Dispensational Eschathology is true then perhaps it is then a question of God's will which is both revealed in a manner that is both sovereign and commanded. And as far as God's sovereign will is concerned Eschathology and Jesus' imminent return will happen regardless of our response towards it, while at the same time the Scripture's given mandate to take care of creation is commanded and therefore at the same time also holds us accountable as to whether we as part of creation yields to it.
Therefore it is our Christian duty as stewards to take care of the environment
