The best minds in the world crack their brains trying unsuccessfully to understand death. The Bible has the explanation. Death came into the world with sin. "Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men..." (Romans 5:12). That one man who first sinned and brought death to earth was Adam. God had warned him that if he disobeyed his Creator he would "surely die" (Genesis 2:17). Adam sinned, and God's Word was fulfilled. All of us that have come after were born into that sinning, dying race of Adam.
The world is busily trying to deny that there is any such thing as sin, but death shows its hideous face on every hand, and stalks every one of us. Refusing to recognize the reality of sin is madness. We have come to a place where we can rewrite the dictionaries and omit many words of long standing in the English language. Sin, perversion, immorality, depravity, judgement, and a long list of others are no longer regarded as having meaning. But one witness refuses to be silent as to man's spiritual problem, death.
As we study Scripture, we learn that the death that God warned Adam of is far-reaching. Physical death with all its sadness is familiar to most of us. But Revelation. 20:14 tells of the final phase of sin's condemnation - death in its full significance - the second death. Revelation 20 is about the great judgement day when those who die without Jesus Christ stand before God for final sentencing. It tells clearly of people being cast into a fiery lake to spend eternity. This is sober beyond words.
The Bible also tells us that one man's death was different than the rest. Jesus Christ had never committed a single sin. And He was more than a man. He was God incarnate. These two facts should make any enquiring mind meditate deeply on the significance of His cross. It all makes sense when we realize that He died on the cross for OUR sins. All who turn from their sin and receive the Resurrected Saviour by personal faith are promised that heaven awaits them when they die. What a way to go.
