The 40 days of this year's Lenten season started this past week, on Ash Wednesday, as Christian faithful all over the world began the spiritual commemoration of the 40 days that Jesus spent in the desert, when he was repeatedly tempted by Satan.

"This year, the wisdom and cautions of Lent are heightened by the violence and uncertainty coming from Ukraine."

Referencing those 40 days spent in prayer and preparation by Jesus ahead of his public ministry, Fr. Jeffrey Kirby, a priest at Our Lady of Grace Parish in Indian Land, South Carolina, told Fox News Digital that Christians should use this period of time to work on their own spiritual renewal.

ASH WEDNESDAY, START OF LENT: WHEN ‘WORLD IS A MESS, WE MUST TURN TO GOD’

They can do this through "prayer, fasting and almsgiving," said Kirby.

The first Sunday in Lent is also called Quadragesima Sunday, which is derived from the Latin words meaning "fortieth," as this first Sunday is exactly 40 days before Easter.

An individual's hands are shown in prayer. Throughout all of Lent, we're urged to "repent and believe in the Gospel," said Fr. Jeff Kirby of South Carolina. 

There are six Sundays in all in Lent, including Palm Sunday.

LENT: WHAT IS IT AND WHY DO WE OBSERVE IT?

The observance of Lent in its entirety keeps the eyes of the faithful on God and on his promises contained in the Bible, said Fr. Kirby, author of the new book, "Glory Unto Glory: A Primer on Ascetical Theology."

"What will we do with the gift of life?"

"On Ash Wednesday, the stark reminder was given that we are dust and unto dust we shall return," he said.

This thought reminds each of us that life itself "hangs in the balance," and that throughout the entire Lenten season we're urged to "repent and believe in the Gospel." 

Our lives today are "juxtaposed" between our birth and our death, he said. 

"What will we do with the gift of life? How will our lives contribute to what Saint Paul called ‘the more excellent way of love'?"

Fr. Kirby said that the death and suffering we see in the continuing war in Ukraine should serve as sobering reminders of the reality of evil and sin.

"The fallenness of the world serves as a constant examination of conscience and a strong reminder, especially during Lent," said Kirby, "of why we need to temper our spirits, seek virtue and aspire to follow the more excellent way of love."
