"A large number have entered the field as canvassers with whom premiums are the only means of success. They have no real merit as workers. They have no experience in practical religion; they have the same faults, the same tastes and self-indulgences, that characterized them before they claimed to be Christians. Of them it may be said that God is not in their thoughts; He has no abiding place in their hearts. There is a littleness, an earthliness, a debasement in their character and deportment, that testifies against them that they are walking in the way of their own hearts and in the sight of their own eyes. They will not practice self-denial, but are determined to enjoy life. The heavenly treasure has no attractions for them; all their tastes are downward, not upward. Friends and relatives cannot elevate such persons, for they have not a mind to despise the evil and choose the good. 5T 402.2"
"The wicked, through the pride of his countenance, will not seek after God: God is not in all his thoughts."
The EGW passage directly echoes the phrase "God is not in their thoughts" from Psalm 10:4, making it an explicit allusion rather than just a thematic parallel. The context in both passages also relates to the wickedness or spiritual deficiency of certain individuals.
