Hebrews was written by Paul . To those who like to mislead and misguide or argue I understand that is 'debatable' . In my mind Paul wrote Hebrews and that is the way I will truthfully try to explain it . Paul was given a life of hardship by our Lord , he was tested and in the end was a new creature . Paul understood ..faith .
Hebrews 11;1-3
Now faith is the substance of things hoped for, the evidence of things not seen. 2 For by it the elders obtained a good testimony.
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.
