WHAT IS FAITH?
Root word: 'Pistis'
Breaking it Down
Faith is often misunderstood as a mere belief. A belief that is usually blind, uncertain and based on a person's wishful 'hope' that something is true, despite the absence of any persuasive evidence. This is such a misrepresentation on what biblical faith actually is!
The root word refers to being fully persuaded. It's about confidently believing and trusting that something is certain, even before seeing the thing for sure. This confidence usually exists because it's based on the character of one who can be relied upon. For example, it's because we're sure that God can be relied upon, that we believe His promise to never leave and forsake His children (Hebrews 13:5, Joshua 1:5). We can be fully persuaded (faith) that His promise is true, even in the darkest situation. This is because we're confident that He's 100% reliable and trustworthy.
When we say we have 'faith', it shouldn't be based on something we're not too sure is certain. It should be based on something that we're persuaded is absolutely true and/or reliable.
Example of not having faith: Tony doesn't think his dad will show up for his basketball game. This is because his dad constantly promises to come to his games, but he never actually shows up. As much as Tony wishes his dad would come, he doesn't really think it's likely to happen at all.
Example of having strong faith: Tony's basketball game starts in 5 minutes time. He's not heard from his dad all day, but he's hanging onto the promise his dad made that he'll be there by the time the game starts. Everybody else is telling Tony that his dad won't make it because of the traffic. Tony is unmoved by the doubts of others. It's because, time and time again, Tony's dad has always come through and made it just before the match started. Even when there's been traffic before, Tony's dad would park up the car, and run to make it to Tony's basketball game.

"Now faith is the assurance of things hoped for, the conviction of things not seen".
"In all circumstances take up the shield of faith, with which you can extinguish all the flaming darts of the evil one"
"By faith Noah, being warned by God concerning events as yet unseen, in reverent fear constructed an ark for the saving of his household. By this he condemned the world and became an heir of the righteousness that comes by faith".
