What is faith, and how does it relate to trust? Are the two terms different? Does one need to have faith to engage in science or benefit from it? What is trust and what is its role in reasoning? These are the questions I will discuss and answer here.
First, we’ll consider the meaning of “faith.” The most prominent use of the term “faith” is in regard to religion, so let’s look at what it means in that sphere and apply that understanding more generally.
For Christians, the model of faith is presented in the Bible. In Matthew 18, Jesus says, “Truly I tell you, unless you change and become like little children, you will never enter the kingdom of heaven. Therefore, whoever takes the lowly position of this child is the greatest in the kingdom of heaven.” (Mt. 18:3-4, NIV) And again, in Mark 10, Jesus says: “Let the children come to me; do not hinder them, for to such belongs the kingdom of God. Truly, I say to you, whoever does not receive the kingdom of God like a child shall not enter it.” (Mark 10:14-15, ESV)
The reason that Jesus holds children up as models to emulate is that they tend to be “intellectually humble” (i.e. naive) and will often accept religious teachings simply, without challenging the adults by asking too many difficult questions. Ask virtually any religious 6-year-old why he believes in God, and you won’t get anything resembling rational, philosophical arguments. He accepts God because that is what his parents and minister have told him. This is faith, and this is Jesus’s ideal model.
