4:11-16 Men's youth will not be despised, if they keep from vanities and follies. Those who teach by their doctrine, must teach by their life. Their discourse must be edifying; their conversation must be holy; they must be examples of love to God and all good men, examples of spiritual-mindedness. Ministers must mind these things as their principal work and business. By this means their profiting will appear in all things, as well as to all persons; this is the way to profit in knowledge and grace, and also to profit others. The doctrine of a minister of Christ must be scriptural, clear, evangelical, and practical; well stated, explained, defended, and applied. But these duties leave no leisure for wordly pleasures, trifling visits, or idle conversation, and but little for what is mere amusement, and only ornamental. May every believer be enabled to let his profiting appear unto all men; seeking to experience the power of the gospel in his own soul, and to bring forth its fruits in his life.

in doing this—not "by doing this," as though he could save himself by works.
thou shalt … save thyself, and them that hear thee—(Eze 33:9; Jas 5:20). In performing faithfully his duty to others, the minister is promoting his own salvation. Indeed he cannot "give heed unto the teaching" of others, unless he be at the same time "giving heed unto himself."
