I issue a direct challenge to you today; when I am so upset that I am frayed around the edges I pray the Jesus Prayer 200 times once a day, and the peace I feel at the end, the lightness I feel at the end warms my soul, and refreshes me.
Because of this I challenge you to pray the Jesus Prayer 200 times. 100 of those times for yourself saying;
Lord Jesus Christ Son of God have Mercy on me a Sinner.
And another 100 Jesus Prayers using the formula for praying for others an example of which is;
Lord Jesus Christ Son of God have mercy on (Person, place, organization etc) and by their prayers have mercy on me.
If you really want to add variety pray for four different people, places etc. 25 times each.
At the end pay attention to yourself how you feel, and your level of peace, and in the peace of your heart I challenge you to commit to this practice once a day.
