How do we know that God's revelation is essential for faith?

God’s revelation is crucial for faith as it is through the illumination of the Holy Spirit that individuals come to know and understand Him. Romans 10:17 states that faith comes by hearing, and hearing by the word of Christ. This emphasizes that without God revealing Himself, no one could genuinely have faith or desire to seek Him. Jesus pointed out that Peter’s acknowledgment of Him as the Christ was not from human understanding but from divine revelation (Matthew 16:17). This highlights that realizing who God truly is involves His initiative to reveal Himself in a way that the human heart can respond positively.
