The sacrifices of God are a broken spirit: a broken and a contrite heart, O God, you will not despise. (Psalm 51:17)
All these things my hand has made, and so all these things came into being,” declares the LORD. “But this is the one to whom I will look favorably: to the one who is humble and contrite in spirit, and who trembles at my message. (Isaiah 66:2)
The LORD is close to the brokenhearted and saves those who are crushed in spirit. (Psalm 34:18)
For this is what the high and lofty One says—he who lives forever, whose name is holy: “I live in a high and holy place, but also with him who is contrite and lowly in spirit, to revive the spirit of the lowly and to revive the heart of the contrite. (Isaiah 57:15)
Absolutely. If a man wanted to fabricate something like a "Lentin" celebration, this ought to be the thing at the top of the list to "give up"...his heart, his pride, his arrogance. Yet, even this can be granted only by God. (Jn 3:27, ICor 4:7) We only stand because He is able to make us stand.
