People die everyday because of sin. At first when God created the world he never had any plans of man to die. Everything changed when Adam and Eve goes against his will. That disobedience brought sin to the world, and the wages of sin is death. Death has become a natural thing in the world.
But the Bible doesn’t just talk about physical death it also puts emphasis on spiritual death, which keeps us apart from God. The good news is that God came to the world to save us through his son Jesus Christ. Jesus died for our sins and rose again the third day to show that death doesn’t have the final say. If we believe and follow His ways, we’ll live with God even after we depart from this earth.
Since then, death became part of life, but is not the end. For those who believe and trust in God, there’s something much better waiting after this present life. That’s why the Bible teaches us to live well and obey God's commandments, which we all know that one day, we’ll be with Him in a place where there’s no pain and agony.
