It's just Jesus, His Father and the Evil One. I beleive lent is a time to enter the wilderness or desert. Maybe that's the temptation that the Evil One offers us-stay busy, prove yourself to God through all the works of fasting and penance. Not that these are bad. The problem comes in when people substituite them in place of knowing themselves well enough that they know where Lent directs them-to the sin or weakness or ruptured relationship with God or others.
Activity can be a great way of running away from the truth about oursleves.
A truth that might scare us. A truth that we feel even God may reject us. I think that's the greatest temptation that Satan pushes. Instead of running around and doing, Lent offers the opportunity to fast from that action and to see not only who we are but also who God is-merciful, loving and ready to forgive. The wilderness offers that to everyone who has the faith in God to enter.
