Heb 11: 1-2
Faith is the principle by which substance is given to hope. This is how we substantiate our hope and as such certain developments spring forth within our environment and they prove the fact that what is not seen have been brought forth by faith.
The man of faith or the man who is in faith is the one who has gone ahead to substantiate the hope that is set before him, thereby giving evidence to what is not yet seen.
The truth of the matter is when the substance of the hope is understood and lived out, then there is a corresponding bringing forth of evidence of what is not seen.
For instance, the wind (air in motion) is not seen, but there is a strong evidence of the existence of the wind as seen on the trees; it is the evidence of things not seen.
It is by living out this that the elders obtained a good report.
In other words, the elders discovered something within the word of God and interpreted the same within their spirits and pragmatically they came up with what I term the empirical validation of the word of God.
Technically, faith is about substance and evidence.
The man of faith has mastered the ability to substantiate the hope that is set before him in a way to give evidence to things not seen or which do not appear.
He has been able to locate the hope within the unseen things (the grace of God, the provision of God and the finished works of Christ, Lordship of Jesus and the present ministry of the Holy Spirit). So my hope, when it becomes faith must give evidence to the unseen realities.
