"Faith such as this is needed in the world today—faith that will lay hold on the promises of God's word and refuse to let go until Heaven hears. Faith such as this connects us closely with Heaven, and brings us strength for coping with the powers of darkness. Through faith God's children have “subdued kingdoms, wrought righteousness, obtained promises, stopped the mouths of lions, quenched the violence of fire, escaped the edge of the sword, out of weakness were made strong, waxed valiant in fight, turned to flight the armies of the aliens.” Hebrews 11:33, 34 . And through faith we today are to reach the heights of God's purpose for us. “If thou canst believe, all things are possible to him that believeth.” Mark 9:23 . PK 157.1"
"Jesus said unto him, If thou canst believe, all things are possible to him that believeth."
Ellen White directly references Mark 9:23 in this passage.
"Who through faith subdued kingdoms, wrought righteousness, obtained promises, stopped the mouths of lions,"
The EGW passage directly quotes Hebrews 11:33-34 as examples of what faith can accomplish.
"And this is the confidence that we have in him, that, if we ask any thing according to his will, he heareth us:"
Both passages discuss the importance of faith in prayer and receiving answers from God. While not a direct quote, the theme of confident prayer based on faith is present in both.
"Faith is an essential element of prevailing prayer. “He that cometh to God must believe that He is, and that He is a rewarder of them that diligently seek Him.” “If we ask anything according to His will, He heareth us: and if we know that He hear us, whatsoever we ask, we know that we have the petitions that we desired of Him.” Hebrews 11:6 ; 1 John 5:14, 15 . With the persevering faith of Jacob, with the unyielding persistence of Elijah, we may present our petitions to the Father, claiming all that He has promised. The honor of His throne is staked for the fulfillment of His word. PK 157.2"
"And if we know that he hear us, whatsoever we ask, we know that we have the petitions that we desired of him."
EGW directly quotes 1 John 5:15 to support her point about prevailing prayer.
"And this is the confidence that we have in him, that, if we ask any thing according to his will, he heareth us:"
The EGW passage directly quotes 1 John 5:14.
"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 directly quotes Hebrews 11:6.
