Fridays in Lent are given to particular prayer practices. You are encouraged to pray in your preferred way every day. Fridays are for experimenting with prayer and seeing prayer as an action.
Today, let’s practice giving alms (donating money) to the poor. This is to actually do what Jesus advised to the young ruler from Monday’s devotion.
See also Matthew 6 for the essence of alms giving:
So whenever you give alms, do not sound a trumpet before you, as the hypocrites do in the synagogues and in the streets, so that they may be praised by others. Truly I tell you, they have received their reward. But when you give alms, do not let your left hand know what your right hand is doing, so that your alms may be done in secret; and your Father who sees in secret will reward you.
