Go forth and preach the Gospel, gain an experience, learn wisdom, and walk humbly before your God, that you may receive the Holy Ghost to guide and direct you, and teach you all things past, present, and to come. 8:176.
Go trusting in God, and continue to trust in him, and he will open your way and multiply blessings upon you, and your souls will be satisfied with his goodness. I cannot promise you any good in taking an unrighteous course; your lives must be examples of good works. 8:73.
I think that the brethren were required to go and preach "without purse and scrip," and that is what I am now trying to get them to do—to go "without purse and scrip," and not beg the poor Saints to death. Let us support the Elders, instead of making the poor do it. We are able to send these men out to preach the Gospel, and they may go "without purse or scrip." 8:169.
I wish the Elders to go forth as I have taught them. If you have a clean shirt and one to be washed, then be satisfied. If you are clothed so as to be comfortable, be satisfied, and do not let your minds reach out after anything, only to preach the Gospel and gather the souls of men. That is all the business you have upon your hands—it is your whole mission; and trust in God to get home—trust in the Lord to go from place to place, and the way will be opened for you. 8:185.
Those who now go forth upon missions will feel more of the power of God than they ever had, and will speak as men having authority, asking no odds of the wicked. 8:172.
I would like to impress upon the minds of the brethren, that he who goes forth in the name of the Lord; trusting in him with all his heart, will never want for wisdom to answer any question that is asked him, or to give any counsel that may be required to lead the people in the way of life and salvation, and he will never be confounded worlds without end. Go in the name of the Lord, trust in the name of the Lord, lean upon the Lord, and call upon the Lord fervently and without ceasing, and pay no attention to the world. You will see plenty of the world—it will be before you all the time—but if you live so as to possess the Holy Ghost you will be able to understand more in relation to it in one day than you could in a dozen days without it, and you will at once see the difference between the wisdom of men and the wisdom of God, and you can weigh things in the balance and estimate them at their true worth. 12:34.
If the Elders cannot go with clean hands and pure hearts, they had better stay here. Do not go thinking, when you arrive at the Missouri River, at the Mississippi, at the Ohio, or at the Atlantic, that then you will purify yourselves; but start from here with clean hands and pure hearts, and be pure from the crown of the head to the soles of your feet; then live so every hour. Go in that manner, and in that manner labor, and return again as clean as a piece of pure white paper. This is the way to go; and if you do not do that, your hearts will ache.
Will you be liable to fall into temptation and be overtaken by sin? Yes, unless you live so as to have the revelation of Jesus Christ continually, not only to live in it today or while you are preaching, in a prayer meeting, or in a conference; and when you are out of these meetings, when you are guarded more particularly by the Spirit, say that you can get along without the Holy Ghost. You must have it all the time—on Sunday, Monday, Tuesday, and every day through the week, and from year to year, from the time you leave home until you return; so that when you come back, you may not be afraid if the Lord Almighty should come into the midst of the Saints and reveal all the acts and doings and designs of your hearts in your missions; but be found clean like a piece of white paper. That is the way for the Elders to live in their ministry at home and abroad. 6:273-4.
I want to say for the consolation of the Elders of Israel and those who go forth to preside, you need have no trouble with regard to the building up of this Kingdom, only do your duty in the sphere to which you are assigned. 14:79.
Elders who go forth to proclaim the Gospel, unless they do something to clip their faith, or cause them to apostatize from their religion, so that they are left in the dark, are generally on the increase in improvement, grow in grace and in knowledge. They are advancing in the principles of truth, while the world are receding from the truth they once had; consequently, it appears to the Elders, and to those who go from the Saints into the world, that it is growing wicked faster than it really is, and the Elders do not always realize that their advancement in truth produces much of the appearance of the great distance between them and the world. 3:221-2.
