Happy Easter to you all! Jesus was talking about the resurrection long before it occurred!
A very important question, and the perfect answer:
“Jesus said to her, ‘I am the resurrection and the life. He who believes in me will live, even though he dies; and whoever lives and believes in me will never die. Do you believe this?’
‘Yes, Lord,’ she told Him, ‘I believe that you are the Christ, the Son of God, who was come unto the world.'”
(John 11: 25-26)
