FAITH
Faith is substance
Hebrews 11:1 Now faith is the substance of things hoped for, the evidence of things not seen.
2 For by it the elders obtained a good report.
3 Through faith we understand that the worlds were framed by the word of God, so that things which are seen were not made of things which do appear.
The world we walk in is seen and unseen. Many people think that this physical world is the full set of what is and cause and result are both in the physical world. This is not true from the very creation of this cosmos all things that are came from the eternal formulated in the unseen [ether] manifest in the physical. This is to say all that we know in the physical has an unseen part and truly is subject to the law of faith and that law is powerful and in place first and rules all this casual cosmos.
Faith is now or it is not Faith
If we hope so it is not faith. When we turn on a light for the first time in a house that we have never been in we hope that the light will come on and are ready to find an alternate source of light. Now when we know that the electric bill is paid and no damage is in the system that we know of we turn the light on in faith expecting that light will be. It is a unseen fact for us that light is on that switch. We have now faith in that switch when the light is off or on. If you were asked how that works you may not even have a clue, but you know it dose work. Faith in God is much the same and it is a now faith.
Faith build this cosmos
God used faith to make this cosmos, He thought or measured this in his hand and spoke it into existence.
