‘Abdu’l-Bahá feels great attachment towards the Chicago friends, for the call of the Kingdom of God, first of all, reached Chicago and made some souls in that city attracted to the Heavenly Kingdom. As in the beginning they did before all attain to the Spirit of Life, so should ye now try to preserve this bounty to the end. Resist ye like unto a firm foundation every violent storm. Withstand ye like unto a strongly-rooted tree the severe winds. Be ye released from every thought save that of the Kingdom of God. Be ye freed from every bond. Have ye no attachment save that to His Holiness Bahá'o'llah. Strive ye day and night with heart and soul so that ye may render some service to the Kingdom of God.
