In considering the principles of the gospel, it will not be difficult to see that faith occupies the first place in the catalogue of righteous principles which, as a whole, go to constitute the plan of salvation. It is the principle existing in the human soul which goes before all action and leads to good works. It pleases God that man should repent of all sin by ceasing therefrom, thus accomplishing a reformation of life without which remission of sins would not be granted; and as repentance and good works are pleasing to God, we must accept of faith first, for Paul says: "But without faith it is impossible to please Him: for he that cometh to God must believe that He is, and that He is a rewarder of them that diligently seek Him." (Heb. xi:6.) "Now faith is the substance of things hoped for, the evidence of things not seen." (Heb. xi:1.) The inspired translation by the prophet Joseph Smith renders the word "assurance" instead of "substance," which appears more consistent with the latter clause in the passage, which says, "the evidence of things not seen," not the substance itself, for that would amount to knowledge or the actual possession of the object hoped for. This assurance of things hoped for must come through some evidence, either of a character which can be demonstrated in a tangible manner, or through some impression which gives an assurance to the mind of the individual possessing it, if to no other. This faith prompts to action all intelligent beings. Without the assurance of reaping, the farmer would not sow; the laborer would not commence his daily task unless he believed he would accomplish it; and so it is in religious matters. Upon the day of Pentecost the multitude never would have appealed to the apostles to know what they should do to be saved unless they first believed in God and in His Son, Jesus Christ--so recently crucified in their midst--and also in the authority of the apostles to teach and administer in the ordinances of eternal life. This faith was based upon the evidence presented by Peter that Jesus was the Christ, sealed upon their hearts by the Spirit of God, and not by the wisdom or ability of man. The result was obedience, and a knowledge of the truth for themselves; for the promise is: "If any man will do His will, he shall know of the doctrine, whether it be of God, or whether I speak of myself." (St. John vii:17.) If Peter had been an impostor, deceiving the people, he might, perchance, have persuaded some to accept his theories; but what would have been the result? The evidence being false, the faith or assurance would have a false foundation to act upon, and disappointment would have been the result. When the evidence is true, the faith resulting and acted upon will bring knowledge.
