A double minded man is unstable in all his ways. –James 1:8 (KJV)

Faith is the substance of things hoped for, the evidence of things not seen. –Hebrews 11:1 (KJV)

It shall come to pass in the last days, saith God, I will pour out of my Spirit upon all flesh: and your sons and your daughters shall prophesy, and your young men shall see visions, and your old men shall dream dreams. –Acts 2:17 (KJV)

The fearful, and unbelieving, and the abominable, and murderers, and whoremongers, and sorcerers, and idolaters, and all liars, shall have their part in the lake which burneth with fire and brimstone: which is the second death.   –Revelation 21:8 (KJV)

[Faith] is the power to see into the world of spirits, into things invisible and eternal.   –John Wesley
