You cannot really be seeking to reflect the image of God within you if you have not renounced selfish motives and personal desires.  Selfless service to everyone around you is the way to attain union with God.  When you overcome both attachment to fulfilling your sensual desires and to the desire to have your actions yield the results that you want, you will be completely identified with the image of God.  True serenity is the state of mind that results.
