Set our hearts on fire with love to you, O Christ our God, that in its flame we may love you with all our heart, with all our mind, with all our soul, and with all our strength and our neighbors as ourselves, so that, keeping your commandments, we may glorify you, the giver of all good gifts.

– Eastern Orthodox Prayer

This is one of the more well-known ancient prayers, but one that is well needed in the day in which we live. Lord make us instruments of your peace.

Lord, make me an instrument of thy peace.
Where there is hatred, let me sow love,
Where there is injury, pardon;
Where there is doubt, faith;
Where there is despair, hope;
Where there is darkness, light;
And where there is sadness, joy.

O Divine Master, grant that I may not so much seek
to be consoled as to console,
to be understood as to understand,
to be loved, as to love.

For it is in giving that we receive,
It is in pardoning that we are pardoned,
and it is in dying that we are born to eternal life.

St. Francis of Assisi

A prayer of St. Francis:

Almighty, eternal, just and merciful God, give us miserable ones the grace to do for You alone what we know you want us to do and always to desire that pleases You. Inwardly cleansed, interiorly enlightened and inflamed by the fire of the Holy Spirit, may we be able to follow in the footprints of Your beloved Son, our Lord Jesus Chris, and, by Your grace alone, may we make our way to You, Most high, who live and rule in perfect Trinity and simple Unity, and are glorified God almighty, forever and ever.

Amen
