They willfully ignore this: Long ago the heavens and the earth were brought about from water and through water by the word of God. Through these waters the world of that time perished when it was flooded. But by the same word, the present heavens and earth are stored up for fire, being kept until the day of judgment and destruction of ungodly men. 2 Peter 3:5-7 HCSB
God's Word is very clear that someday Jesus will return and this sinful world will be judged. Nobody knows the exact time, but we can be assured that it will happen. In Noah's day God brought judgment on the sinfulness of men by flooding the world with water, but when Christ returns the world will be judged by fire (see Revelation 19:20 and 20:10-15).
The same power that formed the earth will also command the day of judgment. God is patient and His love for all mankind and all sinners causes Him to delay the return of Christ so that others might come to know Him as Lord and Savior. Everyone will answer to a Holy God and give an account of his or her life. Those who have rejected Christ as Lord and Savior will be sent to hell, a literal place where they will spend eternity separated from a loving and caring God.
Challenge: Are you ready for Judgment Day? Have you accepted Christ as Lord and Savior? It is as simple as A-B-C: Admit you are a sinner. Believe that Jesus Christ is the Son of God, lived a perfect life, died for your sins, and rose again. Confess Jesus as your personal Lord and Savior.
