The Bible tells us that “it is appointed unto men once to die” (Hebrews 9:27), because “all have sinned” (Romans 5:12).
Originally, the one God created this world in perfection (Genesis 1:31), and the first man and woman (Adam and Eve) were able to completely enjoy life on earth, without the suffering, pain, evil, and death that we experience today.
However, when they disobeyed God (Genesis 3:6), they began to experience the effects of sin that God warned them about – namely, suffering and death (Genesis 2:15-17; 3:16-19). God’s Word tells us that every human since Adam has been born a sinner, willingly perpetuated that sin (Romans 3:10, 23), and reaped its resulting consequences of eternal death (Romans 6:23; Revelation 20:15).
The “good news” (i.e., the gospel – Romans 1:16) of God’s Word is that a “second Adam” has provided salvation for us from sin and death (Genesis 3:15; Romans 5:12-21; I Corinthians 15:45).
God Himself came to earth in the person of Jesus Christ to live a perfect life, to die for our sin in our place, and to rise from the dead, defeating death so that we might be given His perfection and life (II Corinthians 5:21; I Peter 3:18).
