Few people appreciate advice, especially when it is unsolicited.
However, in the interest of the cause of Christ the following suggestions are offered. First of all, never enter evangelistic work if you can keep from it. Only those with an impelling desire to save souls and strengthen saints should consider this type of work. Having entered evangelistic work, expect great things of God, but not of your brethren. Do not be disappointed if congregations or fellow Christians do not share your enthusiasm.
