Keeping Great Lent properly and strictly is always a struggle. Here is one hymn which tells us what to do and what to pay attention to during the Fast.
“Since we know the Lord’s commandments,
let us live accordingly:
let us give the hungry food,
the thirsty drink;
let us clothe the naked,
welcome strangers to our homes,
visit those in prison and the sick;
so that he who will judge the whole earth
will say even to us:
‘Come, you that are blessed by my Father,
inherit the kingdom prepared for you.’”
(Vespers Hymn in Orthodox Lent, Holy Week and Easter by Hugh Wybrew, pp 32-33)
Charity for the poor and needy is the best way to keep Great Lent – it is how we change our hearts to love as Christ loves us.
