Often the question arises, Why, then, are there so many, claiming to believe God's word, in whom there is not seen a reformation in words, in spirit, and in character? Why are there so many who cannot bear opposition to their purposes and plans, who manifest an unholy temper, and whose words are harsh, overbearing, and passionate? There is seen in their lives the same love of self, the same selfish indulgence, the same temper and hasty speech, that is seen in the life of the worldling. There is the same sensitive pride, the same yielding to natural inclination, the same perversity of character, as if the truth were wholly unknown to them. The reason is that they are not converted. They have not hidden the leaven of truth in the heart. It has not had opportunity to do its work. Their natural and cultivated tendencies to evil have not been submitted to its transforming power. Their lives reveal the absence of the grace of Christ, an unbelief in His power to transform the character. COL 9…
"So then faith cometh by hearing, and hearing by the word of God."
Ellen White directly references Romans 10:17 in this passage.
"Sanctify them through thy truth: thy word is truth."
Ellen White directly references John 17:17 in this passage.
"Wherefore by their fruits ye shall know them."
The EGW passage speaks about the lack of reformation in the lives of some believers and connects it to a lack of conversion. This directly reflects the principle in Matthew 7:20, which states that one can be known by their fruits. The absence of good fruit (reformation) indicates a lack of genuine conversion.
"The truths of the word of God meet man's great practical necessity—the conversion of the soul through faith. These grand principles are not to be thought too pure and holy to be brought into the daily life. They are truths which reach to heaven and compass eternity, yet their vital influence is to be woven into human experience. They are to permeate all the great things and all the little things of life. COL 100.2"
"All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness:"
The EGW passage directly echoes the principle of Scripture being profitable for instruction and its application to daily life.
