God is the Creator of heaven and earth. He doesn't only save our souls, He also saves the entire universe. In fact, God's creation is so precious to Him that He is going to create a new heaven and earth. In the meantime, we should look after what God created. We should be good stewards(managers) of this Earth. We shouldn't pollute, we should litter, we should preserve and protect. Are you helping with protecting this creation?
" In the beginning God created the heavens and the earth."- Genesis 1:1
