How do we know God reveals Himself?

God's self-revelation occurs through both Scripture and the Holy Spirit's work in our hearts. In the sermon, it is emphasized that true knowledge of God can only come when He reveals Himself to us. Moses' desire to know God resulted in God showing His glory, illustrating that for us to truly know the way to God, it must be revealed through Christ. As stated in John 6, no one can come to Christ unless the Father draws them, revealing the necessity of divine action in our understanding of God.
