How do we know that God's Word is living and effective?

The effectiveness of God's Word is demonstrated through its ability to engage with our inner being and transform us. Hebrews 4:12 states that it is 'sharper than any two-edged sword,' indicating its capacity to pierce deeply into our souls and discern the very thoughts and intents of our hearts. This means that it does not leave us unchanged; rather, it reveals our spiritual state and brings forth a realization of our need for redemption. The evidence of its living nature is found in personal conversion experiences, where individuals encounter God through His Word and experience profound transformation.
