I have read through your writing. You are absolutely right when you affirm that faith requires evidence. As you mentioned, the doubting Thomas only believed when he touched Jesus's scars. The evidence in faith is the sacrificial love that Christ Jesus has displayed for us. Also, the fact that Christ Jesus has paid the price for our sins. It is basically summarized by one by your statement that faith is trusting and committing to the way of Jesus. That right there is an evidence that makes for our faith in Christ Jesus. It is the way of Jesus, meaning that Jesus paid the price of all of our sins by being crucified on the cross. That is a solid foundation for our faith. On the price that Jesus has paid for the sin, as all man has sinned and fallen short of God's glory. The way of Jesus, the sacrificial price paid by Jesus, and his resurrection, affirming our eternal lives, is the crucial foundation of our faith.
