We should be careful about criticising the conscientious scruples of the saints. No doubt the vegetarian brethren thought they were just as right as the carnivorous brethren. We must be careful lest we find ourselves criticizing God. Guard against thinking too highly of yourself. Do not brag about your own accomplishments, articles, or ability.
Some preachers are prone to think and talk about seniority.
As a preacher of the gospel your task is to talk about Christ, not your fellow preacher. As a good salesman for Jesus Christ you will be constantly looking for new recruits. As you read the newspaper, magazines, and various hooks, be constantly on the alert for ideas, illustrations, and statistics which will be useful in preaching Christ. Be willing to talk to any lost soul at any time. Don't give up while there is life, and don't discourage someone else from talking to someone out of Christ.
