Jesus asks to believe in Him as the Messiah and as Son, appealing for credibility to His works.
After the triumphant entry into Jerusalem, many did not believe in the revelation of Jesus: reflecting, Christ was identifiable with God, because of His words, that are worthy of faith as they are congruent with His divine deeds.
The Nazarenes marveled at the His deeds, yet they remained wary and hostile with pride and disbelief; resisting Jesus, the mighty deeds do not abound and lose their raison d’etre.
Instead, the epileptic boy’s father pleaded for help from Jesus and, hearing that anything is possible for those who believe, asked for help for his disbelief: Jesus works healing and explains to the disciples the potential of faith.
The born blind man was asked to believe, but he wished first to know who had just healed him, then he opened himself to the faith; those who humbly seek God receive the grace of recognizing the Son; on the contrary, those who trust in themselves reject the light that comes from above and condemn themselves to blindness.
Faith in the Son is adherence rather than rejection and His lift up to the Cross is the definitive proof to profess faith in the meeting with the Risen.
Blessed will be those who will believe, because of the signs handed down, that Jesus is the Son of God: they will have life in His name by welcoming the Word and becoming children of God, ready to respond to those who ask reason for hope with righteous conscience and ready to suffer for doing good, rather than doing evil.
