The hymn Enthoten De chanted in English. This hymn is one of many examples of a purely scriptural inspiration of hymnology - being taken from Luke 22;28-30, in which Christ is speaking to the disciples during the Last Supper saying to them "But you who stood with me in my temptations, I will establish with you my Holy Covenant forever. I will let you eat with me on my table in my kingdom. I will seat you on twelve thrones you will judge the twelve tribes of Israel." This hymn provokes the listener to steadfastness and a deliberation in following Christ amidst an environment of struggle and doubt. 
May God bless this Apostles' Fast of 2019, through the prayers of all the apostles and disciples of Christ of whom we are the continuation of.
