When you read the revelations, or when you hear the will of the Lord concerning you, for your own sakes never receive that with a doubtful heart. 3:336.
To explain how much confidence we should have in God, were I using a term to suit myself, I should say implicit confidence. I have faith in my God, and that faith corresponds with the works I produce. I have no confidence in faith without works. 4:24.
My faith is, when we have done all we can, then the Lord is under obligation, and will not disappoint the faithful; he will perform the rest. 4:91.
A great many good people, who possess much of the Spirit of the Lord, are naturally given to doubting, having so little self-reliance that they sometimes doubt whether they are Saints in truth or not. These often doubt when they should not. So long as they are walking humbly before God, keeping his commandments, and observing his ordinances, feeling willing to give all for Christ, and do everything that will promote his Kingdom, they need never doubt, for the Spirit will testify to them whether they are of God or not. There are some who are always fearful, trembling, doubting, wavering, and at the same time doing everything they can for the promotion of righteousness. Yet, they are in doubt whether they are doing the best possible good, and they fear and fail here and there, and will doubt their own experience and the witness of the Spirit to them. 12:169.
When a person is placed in circumstances that he cannot possibly obtain one particle of anything to sustain life, it would then be his privilege to exercise faith in God to feed him, who might cause a raven to pick up a piece of dried meat from some quarter where there was plenty, and drop it over the famishing man. When I cannot feed myself through the means God has placed in my power, it is then time enough for him to exercise his providence in an unusual manner to administer to my wants. But while we can help ourselves, it is our duty to do so. If a Saint of God be locked up in prison, by his enemies, to starve to death, it is then time enough for God to interpose, and feed him. 1:108.
Are you full of faith? You can tell whether I am or not by looking at me. You can tell whether the brethren who have been speaking to you are full of faith in the Gospel by the look of their countenances. You can see this if there is not a word spoken; we can tell by our feelings when we look at a congregation whether they have faith or not. I see there is a great amount of faith in the midst of the Latter-day Saints, and I wish there was a little more patience and obedience. 15:37.
If the Latter-day Saints will walk up to their privileges, and exercise faith in the name of Jesus Christ, and live in the enjoyment of the fulness of the Holy Ghost constantly day by day, there is nothing on the face of the earth that they could ask for, that would not be given to them. The Lord is waiting to be very gracious unto this people, and to pour out upon them riches, honor, glory and power, even that they may possess all things according to the promises he has made through his Apostles and Prophets. 11:114.
When faith springs up in the heart, good works will follow, and good works will increase that pure faith within them. 3:155.
The expression, "true believer," needs qualifying, for many believe who do not obey—I will qualify it by saying, a believer in Jesus Christ, who manifests his faith to God, angels, and his brethren, by his obedience. Not but that there are believers who do not obey, but the only true believers are they who prove their belief by their obedience to the requirements of the Gospel. 1:234.
Our Heavenly Father does not always reveal to his children the secret workings of his providences, nor does he show them the end from the beginning; for they have to learn to trust in him who has promised to fight our battles, and crown us with victory, if we are faithful as was faithful Abraham. 11:13.
