Did I not tell you that if you believe, you will see the glory of God?
Jesus in the resurrection of Lazarus (John 11) speaks with Martha, the sister of Lazarus; and says: "Did I not tell you that if you believe, you will see the glory of God"?. Expressions referring to seeing or perceiving either the kingdom of God or God are frequent in the gospels, for example: "Very truly I tell you, no one can see the kingdom of God unless they are born again" John 3:3.
The teachings of Jesus have a similarity with the teachings of Plato, both authors explain that there are objects that can be perceived by the senses such as physical objects and objects that can only be perceived with intelligence, these are the immaterial entities.
Jesus, teaching to us about the spirit, tells us about perceiving God and his divine attributes (such as eternity) with the intelligence, with the gift of knowledge: "Now this is eternal life: that they know you, the only true God", John 17:3. Jesus asks Marta, not the simple faith that comes from accepting the creed, (the creed is a series of statements that constitute the basis of religious doctrine, for example in the Catholic religion is in catechesis and liturgy), but of that faith that comes from knowledge and experience, adult faith.
The resurrection of Lazarus reminds us of the importance of trust in God, God works in us through his perfections, that is, his gifts. Jesus as "son of man", as a personification of the perfections of God ("I am the resurrection and the life"), teaches us the gift of the resurrection, that is, the perfect immortality:
"Jesus, once deeply moved, came to the tomb. It was a cave with a stone laid across the entrance. "Take away the Stone", he said.
"But, Lord", said Martha, the sister of the dead man, "by this time there is a bad odor, for he has been there four days".
Then Jesus said, "Did I not tell you that if you believe, you will see the glory of God?"
So they took away the Stone. Then Jesus looked up and said, "Father, I thank you that you have heard me. I knew that you always hear me, but I said this for the benefit of the people standing here, that they may believe that you sent me.
When he had said this, Jesus called in a loud voice, "Lazarus, come out!". The dead man came out, his hands and feet wrapped with strips of linen, and a cloth around his face.
Jesus said to them, "Take off the grave clothes and let him go." John 11:38-45
