John 14

John 14:6 Jesus said to him, "I am the way, and the truth, and the life; no one comes to the Father but through Me.”
You are the master of your own earthly life. If you chose not to love and follow God, after your body dies, your spirit will live on separated from God. That’s a horrible existence without anything good.
Jesus says that He is life, and He can give you life with God forever. If you choose to love and follow Jesus, He will give you life with Him forever.
