I'll share how my faith was increased/developed. God gives every man a measure of faith to receive Him. We receive Him initially, but it's not a one time thing. Every breath of inspiration that comes from Him, we receive Him some more. God is Spirit, His Son is Spirit, and He communes with us via His Spirit and His Word.
When I first received Him, I didn't know if the Word was God inspired, or man written alone. I literally didn't realize there were two books; I thought it was all one. One of the ways my faith was increased right off the bat, was to start studying the original languages. My eyes were opened when I saw that everybody's name in there meant something that was significant to our walk with Him. It was astounding to me, and proved beyond a shadow of any doubt (the opposite of faith) that God was active in the lives of men and women. Even the names of the places and things had significance.
Then I read in the NT that the things they went through were for OUR example! No wonder the OT names were significant. Studies have shown that most people learn best through repetition. The One who made us, knew this, and He made sure that He kept repeating the same lessons in different contexts over and over again, so we'd "get" it!
The next thing that was a faith builder for me, was to "stand" on scriptures. I reasoned that if salvation was a real spiritual experience and I had no doubt it was, because I was different from one day to the next and everyone around me could see it, then I decided to see if another scripture was real, and specified which one I was "testing". I did this over and over again, asking Him to show me, and He did. I was like a child stepping on stepping stones in a river, testing the strength of each one as I stepped on it.
Then as I grew, once I saw that the baptism of the Spirit and the gifts of the Spirit were part of OUR covenant, and that God was no respecter of persons, meaning there is not one covenant for 1st century Christians and another one for us, I asked for and received those. They are for everyone in this covenant, but not everyone chooses to believe that. I told God I wanted all of Him I could get, and I didn't care what that entailed. I also read He said He would teach us and give us wisdom. I asked for that. It is His great pleasure to give His children gifts and He gives to all who ask, liberally!
The gifts are designed to BE faith builders, in both ourselves and in those around us. We are told to build up our MOST HOLY FAITH, by praying in the Holy Ghost. It is in this we find that there are different levels of faith, just like there are different stages of growth in the natural realm.
There's a wealth of faith building that goes on in that realm that would require a much longer post, including healings, but these are the primary steps He took me through. Blessings....
PS. I was looking for my testimony post to add here, but it must have disappeared in one of the board crashes over the years. Oh well.....
