"It is not always the most learned presentation of God's truth that convicts and converts the soul. Not by eloquence or logic are men's hearts reached, but by the sweet influences of the Holy Spirit, which operate quietly yet surely in transforming and developing character. It is the still, small voice of the Spirit of God that has power to change the heart. PK 169.1"
"And my speech and my preaching was not with enticing words of man’s wisdom, but in demonstration of the Spirit and of power:"
Both passages contrast outward displays of power with the quiet, inner work of the Spirit. EGW connects the 'still small voice' with the Holy Spirit's influence, while 1 Corinthians 2:4 emphasizes the Spirit's demonstration over human wisdom.
"“What doest thou here, Elijah?” the voice inquired; and again the prophet answered, “I have been very jealous for the Lord God of hosts: because the children of Israel have forsaken Thy covenant, thrown down Thine altars, and slain Thy prophets with the sword; and I, even I only, am left; and they seek my life, to take it away.” PK 169.2"
"And he said, I have been very jealous for the Lord God of hosts: for the children of Israel have forsaken thy covenant, thrown down thine altars, and slain thy prophets with the sword; and I, even I only, am left; and they seek my life, to take it away."
EGW directly quotes 1 Kings 19:10.
