"“This is the victory that overcometh the world, even our faith,” [ 1 John 5:4 .] It is faith that enables us to look beyond the present, with its burdens and cares, to the great hereafter, where all that now perplexes us shall be made plain. Faith sees Jesus standing as our Mediator at the right hand of God. Faith beholds the mansions that Christ has gone to prepare for those who love Him. Faith sees the robe and crown prepared for the overcomer, and hears the song of the redeemed. GW 259.3"
"For whatsoever is born of God overcometh the world: and this is the victory that overcometh the world, even our faith."
Ellen White directly references 1 John 5:4 in this passage.
