Jesus says in our Gospel blessed are those who have not seen, and believed.
One of the things that this line from Christ implies is that even though He promises to be present in every Sacrament of the Church, we should not expect to ever SEE Him, rather He says that we are blessed if we still believe in Him without actually seeing Him.
Saint Paul puts it this way to the Romans in chapter 8 verses 24 and 25: “hope that sees for itself is not hope. For who hopes for what one sees? But if we hope for what we do not see, we wait with endurance”
It is also Divine Mercy today and at the bottom of the Divine Mercy image is 5 words, “Jesus I trust in you.” Trust and hope go hand in hand. One can only trust if they have not been let down by the other person. The moment the person asking for trust lets us down, it is hard to reestablish that Trust. But Jesus always and everywhere keeps his promises, so when Jesus asks us to trust Him, it makes sense for us to trust Him.
There are over 100 Eucharistic Miracles that have been approved by the Catholic Church, usually because of a doubt in the priest’s mind, where the bread at the consecration did actually turn into physical flesh or the wine, at the consecration, became physical blood. But I have always thought that God, in His Mercy, does not reveal Himself that way 99.9999% of the time SO THAT WE CAN STILL EAT and receive him into our body and souls. Sometimes we think it might be nice to see a Eucharistic Miracle like that, but would anyone want to actually eat Jesus’ skin?
So let us put our trust in Christ when He says to us “Blessed are those who have not seen and still believe”
