Biblical explanation
Jesus spoke of the end of the age and His return (Matthew 24:3). Peter describes the final day of judgment and says: "the heavens shall pass away with a great noise, and the elements shall melt with fervent heat." 2 Peter 3:10, KJV But Scripture does not end with destruction. Peter continues: "Nevertheless we, according to his promise, look for new heavens and a new earth, wherein dwelleth righteousness." 2 Peter 3:13, KJV Revelation gives the same ultimate picture: "I saw a new heaven and a new earth." Revelation 21:1, KJV God's purpose is therefore not merely to destroy but ultimately to restore. The Bible does not give a modern scientific description of exactly how every physical process will occur. It does clearly teach: Christ returns. Judgment occurs. Evil is finally destroyed. God creates a renewed world. God's people dwell with Him forever.
Key takeaway
Discipleship applies the gospel to the whole life: body, mind, relationships, work, finances, and worship. Healthy choices and faithful habits do not earn salvation; they are grateful stewardship of the life God has entrusted to us and practical ways to serve others.
