The answer is: New Testament

Only appears twice in KJV O.T.

Did you know that the word "faith" truly shines brighter in the New Testament than in the Old? While it only makes a brief appearance twice in the King James Version of the Old Testament, the New Testament brings faith to the forefront — using "faith" over 200 times! It's like comparing a flickering candle with a dazzling sun.

Interestingly, in the Old Testament context, the two instances primarily revolve around steadfastness and trust rather than the New Testament's broad-spectrum interpretation that plumbs the depths of belief, trust in Christ, and faith as a communal journey. The Old Testament emphasizes faith in God within the grander narrative of covenant promises and deeds done.

Now, to add a bit of trivia: one of the Old Testament mentions of faith is in Habakkuk. The prophet writes, “the just shall live by his faith” (Habakkuk 2:4), a verse quoted in the New Testament to capture the essence of righteous living through faith, echoing throughout Paul's letters.

Fast forward to the New Testament, you'll find fingerprints of faith all over. Think about the transformative tales of healing - from the woman with the issue of blood to the centurion's servant. These narratives place an empowering focus on faith as a means to connect individuals with the divine, emphasizing its importance not just as belief, but as something that actively unfolds through action and relationship. So, whether it's small like a mustard seed or vast as an ocean, faith finds abundant life by the time we reach the New Testament!
