HOW SHOULD I LIVE TODAY IN LIGHT OF ETERNITY?

What we think about heaven determines how we live today. We can easily be led away from God’s purposes if we do not steadfastly pursue the things of God and His will (2 Peter 3:17); and without diligence, we can be lulled into apathy and ungodliness, which bring no joy to God or to our personal lives. C. S. Lewis once said, “If you read history you will find that the Christians who did most for the present world were just those who thought most of the next.”6
How do we become effective for Christ in our present world? We must make sure that our lives are matching the purpose for which we were created. We must be diligent to pursue God’s righteousness through the Word, prayer, purity, and seeking His will. That’s the way to live in light of eternity—in light of the “glorious appearing of our great God and Savior” (Titus 2:13).
The grace of God that brings salvation has appeared to all men, teaching us that, denying ungodliness and worldly lusts, we should live soberly, righteously, and godly in the present age, looking for the blessed hope and glorious appearing of our great God and Savior Jesus Christ.
