This picture is really cool. It really describes the Christian who wants to take care of the earth because God has given it to us to master. It is not a matter of owing it to the earth, but being a good steward of God's wonderful gift to us. Remember, if you are God's child, this earth is not our home. We are just passing through to our eternal home in heaven. Take good care of this place here, but don't invest everything in it. It cannot be taken with.
My pastor always says - "There are two things that last forever; God and people. Invest in what is eternal."
