"I had found it difficult to enjoy religion in the seminary, surrounded by influences calculated to attract the mind and lead it from God. For some time I felt a constant dissatisfaction with myself and my Christian attainments, and did not continually realize a lively sense of the mercy and love of God. Feelings of discouragement would come over me, and this caused me great anxiety of mind. LS 26.2"
"Draw nigh to God, and he will draw nigh to you. Cleanse your hands, ye sinners; and purify your hearts, ye double minded."
The EGW passage describes a feeling of distance from God and a desire for a closer relationship, which directly reflects the principle in James 4:8 of drawing near to God.
"For the flesh lusteth against the Spirit, and the Spirit against the flesh: and these are contrary the one to the other: so that ye cannot do the things that ye would."
Both passages describe an internal struggle. EGW describes a struggle to maintain faith amidst worldly influences, leading to discouragement. Galatians 5:17 describes the conflict between the flesh and the Spirit. While not a direct quote, the thematic parallel of internal conflict is present.
