Oh I can answer that:
It started because I was raised to believe, but like every healthy Christian I had to come to my own faith, and several things bolstered it:
The idea of the incredible complexity of creation appearing WITHOUT a creative and intelligent force behind it takes MORE faith than to believe in God.
The historicity, archaeological evidence, and consistency of the Bible in context, including the evidence for the actual resurrection of Jesus.
The impervious logic of Jesus' words coupled with His recorded actions.
The observance of minor miracles in the live of myself and others (too many "serendipitous coincidences" along with surprising healings).
Personal experience, spiritually, emotionally, and psychologically.
God used all of this to convince me if the Truth of His Word. I HOPE that He will do the same for you, my friend! 🫶🏻
