FAITH is the substance of things hoped for, the evidence of things not seen.

VERSE 3:   By faith we understand that the worlds were framed by the word of God so that the things which are seen were not made of things which are visible.

HEBREWS 10:23

Let us hold fast the confession of our hope without wavering, for He who promised is faithful

HEBREWS 10: 35&36
