Hebrews 11:1

Now faith is the assurance (title deed, confirmation) of things hoped for (divinely guaranteed), and the evidence of things not seen (the conviction of their reality-faith comprehends as fact what cannot be experienced by the physical senses).

Believing in Jesus and our salvation was our first step of faith. We believe in what we can’t see, but we know we are saved because of the promise from the word of God. Faith is step one to moving the mountain and believing that what God says in the Bible is real even if we can’t see it. Faith believes that the promises of God are real.
