John 3:16 says that God loves the world and He doesn’t want us to be separated from Him. This verse describes that separation as “perishing” or suffering. In other words when we are separated from God we are disconnected from the ultimate source of life. That means the end result of that separation is death. But God wanted humanity to live forever in relationship with him. So he sent His Son, Jesus to help us understand God’s will and to reconnect us back to God giving us the ability to live forever.
The most amazing part about Jesus coming to earth was his willingness to “perish” or suffer in our place. He took the result or penalty of sin upon himself, and willingly went to a cross to die in our place so we would never have to experience death as a permanent separation from God. In fact he proved that physical death would not be permanent by rising from the dead himself (Romans 5).
His death and resurrection cleared the only possible path for all humanity to return to a relationship with God. That’s why He said that He was the only way to God (John 14:6) because nobody has ever made the path back to God more accessible. The amazing thing is that the reason He did that, was simply because He loved you!
