New Testament Key Words: Believe

A Necessary Connection

The word from the New Testament most commonly translated as “believe” in English is the Greek word pisteuo. In that original language, this word is merely the verbal form (action) of the noun pistis which is most commonly translated as “faith.” The connection between these two words is of paramount importance to the proper understanding of both.

English Confusion

In English, it has become common to separate the concepts of “to believe” and “faith.” For many, faith is considered to be some elusive, intangible, and abstract concept with one simply “holds” or “feels” based upon a “leap.” In contrast, choosing “to believe” is seen as an act for those who have perhaps been motivated by “faith” to demonstrate such belief before the world but not as a necessary demonstration.

The Action of Faith

The reality is that the term “to believe” simply describes the action of “faith.” If one claims to have “faith” they will, through their actions “believe.” One cannot have one without the other for they are, in reality, both the same thing. One cannot claim to have “faith” without believing in God, or without believing the full inspiration of the Bible, or without believing in the power of the Gospel, etc.

It is this choice to believe that holds the power behind faith. In quoting the Old Testament, both Paul and James explain that “Abraham believed God, and it was credited to him as righteousness” (Rom. 4:3; Gal. 3:6; James 2:23; NASU). Does this mean that Abraham had merely a mental assent and called such thoughts faith, or something more? His faith was shown through his actions – his choice to believe.

What Belief Demands

Of course, simply choosing to believe in the reality of God and Christ does not bring God’s approval. James explained that “the demons also believe, and shudder” (James 2:19). However, choosing to believe is a key first step toward obedience. How can one accept the saving power and Lordship of Christ without believing in His power? How can one trust in Christ’s blood to wash away their sins without believing it its power?

It is for this reason that Jesus stated without equivocation “unless you believe that I am He, you will die in your sins” (John 8:24). If you do not believe that Jesus is the Christ, in the power of the Gospel, in the purpose of the church, etc. you cannot have faith. Because faith requires that you choose to believe.
