"(But) take care not to perform righteous deeds in order that people may see them; otherwise, you will have no recompense from your heavenly Father." -- Mt 6:1
It's hard not to crave the notice of your peers. I guess that betrays a certain lack of trust or faith.
But it requires a lot more trust and faith to believe transubstantiation has occurred during the consecration at Mass. We have to trust the Magisterium of our day and Tradition of ages long ago and a reading of Scripture that says that which our eyes perceive and which our tongues taste is truly the Body and Blood, Soul and Divinity of Our Lord Jesus Christ. That's faith! And it should teach us something. "Master, to whom shall we go? You have the words of eternal life. We have come to believe and are convinced that you are the Holy One of God." Jn 6:68-69

"Your Father knows what you need before you ask him." -- Mt 6:8
We can pray, and through prayer we can establish a personal relationship with God. And so Jesus taught us how to pray, "This is how you are to pray: Our Father..." (Mt 6:9)
