Then I saw a new heaven and a new earth, for the first heaven and the first earth had passed away. - Revelation 21:1, NIV
Planet earth is, at the very least, thousands of years old. Some think it may be millions or billions of years old. And it is showing signs of age. It is getting frayed and worn out. It is being polluted, gouged, stripped, burned, and poisoned, and much of the damage has been willfully and selfishly inflicted by man. But some of the scars are simply due to the wear and tear of age. It was not created to last forever!
In contrast, our heavenly home is going to be brand-new. Not just restored, but created fresh.
What scars of sin or stains of guilt do you bear in your life? . . . in your emotions? in your personality? in your relationships? in your memories? Like planet earth, do you feel abused and gouged and worn out and burned by other people? One day there will be no more scars. Everything – including your heart, mind, emotions, psyche, and memories, past, present, and future – will be made new.
