I looked up the word “faith” in my Strong’s Concordance/Vines Bible dictionary and this is
In the Greek, the most used word for faith is pistis, which deals the concept of truth or the truthfulness of God.
The word “faith” in the King James Bible is used mostly in the New Testament. In the KJV it is used twice in the Old Testament. Once in Deuteronomy 32: 20 where Moses is describing the Children of Israel that came out of Egypt as having no faith. The other use is in Habakkuk 2:4 “the righteous one will live by his faith.” (HCSB)
The number of times the word “faith” is used in the KJV is interesting – 247. It might be trying to tell us something. Faith should be a 24/7 thing in our lives.
The spelling of our English word also carries an interesting message. The letter “I” is in the middle of the word. So “I” better stay in faith.
