Consider this prayer from Howard Thurman:
“Lord, make me an instrument of Thy Peace.” Teach me how to order my days that with sure touch I may say the right word at the right time and in the right way — lest I betray the spirit of peace. Let me not be deceived by my own insecurity and weakness which would make me hurt another as I try desperately to help myself. Keep watch with me, O my Father, over the days of my life, that with abiding enthusiasm I may be in such possession of myself that each day I may offer to Thee the full, unhampered use of me in all my parts as “an instrument of Thy Peace.” Amen. – Howard Thurman
Lord, show me how I can be an instrument of your peace today.
