How do we know God speaks to us?

God communicates with humanity in various ways. Primarily, He speaks through His Word, as the Bible is the inspired revelation of God to man, designed to convey His truth. Hebrews 1:1-2 outlines that God spoke through prophets in times past, but now speaks through His Son. Additionally, God reveals Himself through creation, as Romans 1:20 states that His eternal power and divine nature are clear in the created world. Lastly, God communicates internally through the Holy Spirit, applying the truth of His Word to our hearts, guiding us in faith and understanding.
