What is the definition of faith according to the Bible? The Bible provides a clear and concise definition of faith in Hebrews 11:1 NKJV: "Now faith is the substance of things hoped for, the evidence of things not seen." This verse highlights several key aspects of faith: Substance of Things Hoped For: Faith gives substance to our hopes, making them more than mere wishes; it’s a confident expectation based on God’s promises. Evidence of Things Not Seen: Faith acts as the proof or conviction of realities that are not visible to the naked eye. It is the assurance that what God has said will come to pass, even when we cannot see how. Trust in God’s Character: Faith is fundamentally about trusting in the nature and character of God. Hebrews 11:6 NKJV further states, "But without faith it is impossible to please Him, for he who comes to God must believe that He is, and that He is a rewarder of those who diligently seek Him." This biblical definition of faith emphasizes that it is not just belief in a set of doctrines, but a deep trust in God’s promises and His ability to bring them to fulfillment.
