For momentary, light affliction is producing for us an eternal weight of glory far beyond all comparison, while we look not at the things which are seen, but at the things which are not seen; for the things which are seen are temporal, but the things which are not seen are eternal. (2 Corinthians 4: 17,18) NASB
Because we are believers in the Lord Jesus Christ and His promises, All of us are called to change the world in which we live in. C.S. Lewis gave a helpful point of view on a Christian remaining heavenly minded while continuing to make an influence in this present world. Lewis said this:, “In mere Christianity, hope means a continual looking forward to the eternal world. What it does not mean is this: “We are to leave the present world as it is”. The devil and his imps never stop working and as God’s redeemed we should not either. When we read history we can will find that the Christians who did most for the present world were the ones who thought most of the next world. It is since Christians have largely ceased to think of the other world (Our Eternal Home) that they have become so ineffective in this present world. Let us set our sights on Heaven and we will get what we need on this earth thrown in. Set sights on just at the earth and you will not get neither one.
Being heavenly minded is not natural or normal to the carnal people of this old world. To be heavenly minded happens when our focal point and meditation is on the realism and the blessed hope of the world to come. When we do this, we can bring a taste of heaven to the world around us. So let's not become complacent and content on how this present world is. We need to stay focused on our Heavenly home, so we can be effective here on this world we live in. We must occupy until our lord comes.
