first question, I dunno why would you? I said belief is the first step. I believe metal sinks in water. I have faith a boat of metal won't. If I worked on what I believe I wouldn't board the boat. After I test the belief and it's verified it did work, I begin to have faith. I still have issues/concerns, but each time I TRUST, the faith grows. It even works on Pavlov's dogs.
Not believing to believing? That's knowledge. I guess you first have to be told/educated. Then that validated.
Seriously, a person witnesses God. That means they know a Loving Xian. That's a rare bird these days. They experience God's love, that is information.
They see creation, that is a biblical example of information, or God's witness.
The word is on their heart, that's another biblical witness of God's witness.
The Holy Spirit works, not in, but on, them.
They receive the info, they start to test the waters, they trust, they get validation, they grow faith.
If abraham had the knowledge of his son Isaac, but never marched up the mountain, james ch 2 says he would NOT be the "father of faith". It was the action that established the faith.
