Jacob again quoted Isaiah (Isaiah 55:1-2), this time concerning the availability of gospel blessings. When the Old Testament (or Book of Mormon) prophets declared that “salvation is free” they were declaring the same doctrine that others of the prophets have called “salvation by grace.”
Jacob implored all people—all that thirst for happiness, that thirst for peace, that thirst for the assurance of eternal reward and glory hereafter—to come to the waters of life, to the true Church through God’s legal administrators.
He warned them against laboring in causes of doubtful worth and questionable productivity, so far as eternal things are concerned; against spending time and resources in pursuit of false Christs—false systems of religion; against needlessly giving all that a person has to support enterprises which will not satisfy, when he could give himself to the true cause of Christ. Jacob encouraged his listeners to come unto the Holy One of Israel: for he that cometh unto Christ shall never hunger nor thirst ( see John 6:35).
