There are those that claim that religious truth is found in Scripture, be it the Bible, the Quran, The Bhavagad Gita, the Principia Discordia, or other sacred texts.
My question to you is this: Is it better to learn from a subject's biographer, or from the subject Him/Her/Itself? In other words, would you trust a man's writings about God to learn about Him/Her/It, or would you rather learn from God Him/Her/Itself by way of meditation, prayer, or your own personal research?
I my case as a child I studied the scriptures extensively; this has continued all my life.
The thing is that once you get the gist of what things are about, a person starts learning, having experience, in life with how things work. You cannot come to an accurate knowledge without the writings, you cannot come to know God without this.
However, living the Christian life, one goes through obedience and disobedience from being a youth to being old. In this, it becomes obvious to the Christian who isn't disapproved that serious disobedience is punished seriously, and prayers are answered.
So, your question 'scripture or experience' becomes 'scripture and experience.' You learn about God from scripture, but you have personal experience with God from experience, his love, his kindness, his mercy, his loving kindness (the paying back part), and his forgiveness if the sin isn't to death.
His refinement is the hardest of all.
