"David despaired of a reconciliation with Saul. It seemed inevitable that he should at last fall a victim to the malice of the king, and he determined again to seek refuge in the land of the Philistines. With the six hundred men under his command, he passed over to Achish, the king of Gath. PP 672.1"
"And David said in his heart, I shall now perish one day by the hand of Saul: there is nothing better for me than that I should speedily escape into the land of the Philistines; and Saul shall despair of me, to seek me any more in any coast of Israel: so shall I escape out of his hand."
The EGW passage directly reflects the narrative and David's thought process as described in 1 Samuel 27:1. It's more than a thematic parallel; it's a restatement of the biblical account.
"that God permits to come upon them as things that are against them, and that will only work their ruin. Thus David looked on appearances, and not at the promises of God. He doubted that he would ever come to the throne. Long trials had wearied his faith and exhausted his patience. PP 672.2"
"Now faith is the substance of things hoped for, the evidence of things not seen."
EGW's statement about David looking at appearances and doubting God's promises echoes the theme of faith as the substance of things hoped for, the evidence of things not seen. While not a direct quote, the underlying principle of trusting in God's promises despite outward circumstances aligns with the message of Hebrews 11:1.
