Faith is believing in or about someone or something something even though they/it aren't showing evidence of it.
Hebrews 11:1 "Now faith is the substance of things hoped for, the evidence of things not seen". so what that is, is your consciousness/ awareness or thoughts/word/ imaginations about it is that substance.
I remember a few years ago i had to practice faith on an investment that i made because it seemed as though as soon as i made the investment and put up higher offers to sell them their value started to fall like a rock. For 2 straight weeks it did nothing but fall as my offers just sat there stale. By the second week prices had bottomed out at such a low value that on the chart it looked like it would take at least half a year to return to any type of normalcy. I remember just watching it the first week, every day just watching it fall lower and lower and being more and more annoyed because of it. After the week was over i was completely agitated but i made a conscious decision for the next week to just leave my offers in as they were, but i would call them something they were not (sold at the price that i had set previously) regardless of the images that i was shown. During that time i would tell myself things like " im so thankful that my investments have sold" while having the image of them being sold in my mind. I did this all the way until the last day of the 2nd week, and at the end of that day i had decided just to check on the graph and charts one final time, except this time before even looking at it i said " even if this says that they didn't sell im not changing my mind, nor am i going to react to it's reports". I looked and it was still at a horribly low price. I said to myself "Like i said before, you can show me whatever you want but you're still sold at what i have been saying all this week". After saying that i logged off the sites and turned off my computer and went to sleep.
I slept for about 6 hours and woke up early because for some reason i just didn't feel tired anymore, so i logged back in to check my emails and to my surprise something had sold. When i looked closer i was even more surprised because all of my offers had sold at the exact price i had set. I couldn't believe it so i had to check the graphs again to see if it was just a fluke or a glitch. What was funny was the graphs and reports still said that the price was at that low price hat i had seen just before i went to sleep. It wasn't till a few minutes later that it showed how the value had skyrocketed.
I was told later that the price had risen so fast and so unnaturally that the site's graphs and charts couldn't even register it fast enough.
Faith is basically a combination of what i did and what sub and lynx said there because i had to live as though it was done even though i saw no evidence in the natural, and i didn't get to see any evidence of what i hoped for until i was fully committed and unwilling to accept any other imaginations about it.
