Faith is the substance of things hoped for, the evidence of things not seen. Faith is the substance or assurance of things we hope for, but have not yet received. Faith (confidence, belief, trust) is also our evidence of that which is not seen—the invisible spiritual things. Faith comes before a prayer is answered or before an individual has received what he or she has requested from YHWH. If we have received what we asked for, then faith is not needed.
In Matthew 9:27-30 where two blind men came to Yahushua and asked Him to heal them. Yahushua first asked them, “Do you believe that I am able to do this?” and their reply was, “Yes, Master.” “Then He touched their eyes saying, ‘According to your faith let it be to you.’ And their eyes were opened.”
Their faith and assurance that Yahushua could give them sight was the substance or reality they hoped for. It also gave them the evidence or trust that they would receive what they asked for. They believed; that is, they had faith in advance that it would be done.
THEY LIVED BY FAITH, NOT BY SIGHT! (no pun intended)
