"a being must be, and imagined that I could cast myself into the arms of, and trust in the mercy of, such a one. But the question arose, How can it be proved that such a being does exist? Aside from the Bible, I found that I could get no evidence of the existence of such a Saviour, or even of a future state.... GC 319.1"
"But without faith it is impossible to please him: for he that cometh to God must believe that he is, and that he is a rewarder of them that diligently seek him."
The EGW passage describes the need for evidence of God's existence and a future state, which directly relates to Hebrews 11:6's assertion that belief in God's existence is necessary to please Him.
“I saw that the Bible did bring to view just such a Saviour as I needed; and I was perplexed to find how an uninspired book should develop principles so perfectly adapted to the wants of a fallen world. I was constrained to admit that the Scriptures must be a revelation from God. They became my delight; and in Jesus I found a friend. The Saviour became to me the chiefest among ten thousand; and the Scriptures, which before were dark and contradictory, now became the lamp to my feet and light to my path.

"Miller publicly professed his faith in the religion which he had despised. But his infidel associates were not slow to bring forward all those arguments which he himself had often urged against the divine authority of the Scriptures. He was not then prepared to answer them; but he reasoned that if the Bible is a revelation from God, it must be consistent with itself; and that as it was given for man's instruction, it must be adapted to his understanding. He determined to study the Scriptures for himself, and ascertain if every apparent contradiction could not be harmonized. GC 319.3"
"Prove all things; hold fast that which is good."
The EGW passage describes Miller's approach to studying the Bible, which involves examining it critically and seeking to resolve contradictions. This aligns with the principle of 'proving all things' in 1 Thessalonians 5:21.
