How did you come to faith?
I was born with faith, which is God's gift of morality and its conscience. That mustard seed turned into the tree only through never forsaking God's voice from within, conscience. The few times in my life that it warned me don't do this, I stopped.
The question you probably are more curious about is "How did the Holy Spirit enter your heart?"
In the early 1990s I was almost addicted to born again online chatrooms. A stranger had given me a red letter NIV bible. That bible would open for me. At the time I was working very long days which left little time for reading. I started by reading JOB. Then over a span of serveral months, I casually read and reread (not in any specific order) the red letter sections, which turned out to be the four gospels. During that time I would visit chatrooms and speak from my heart. It began apparent that the words from my heart were in accordance with the gospels but contradicting scripture postings from the other books of the new testament.
One Tuesday during that time a stranger had sent me an testimonial email. Basically he testified that he used to be Catholic, then became Christian, and then proclaimed to me that he was now an atheist. He said that after reading the scripture with Peter pointing out to Jesus that the tree which Jesus cursed yesterday is now dead and withered, he could not be a member of any religion that curses and kills an innocent tree. Without even thinking I immediately responded: "May God have mercy on your soul."
I then immediately went to the bathroom (my then reading room) with my bible. It opened to the heading, TEACHINGS FOR TUESDAY.
I thought: "cool its Tuesday" so that's where I read. It turned out to be the exact scripture from the atheist's testimonial. When I read Jesus' response, "Have faith in God" That is the exact moment the Holy Spirit entered my heart.
Approximately five years later, one of my long time customers told me that he noticed a change in me and asked me for my bible. At that time I already owned over a dozen different bibles in several translations. When I tried to give him one of those he said: No, I want that one. He wanted the bible that was opening for me, the one I was reading when I received the Holy Spirit and I didn't want to give it to him. But, then I shook my head and thought what am I doing, the bible is not my idol. I said here take this, God bless you, and gave him my favorite bible. That's the first time that the Holy Spirit's presence in my heart grew even stronger.
