How do we know that God's warnings in the Bible are relevant today?

The warnings found in the Scriptures, including the prophet Joel's messages, are as relevant today as they were in ancient times. Joel 1:2-3 points out the importance of heeding God's word across generations. The call to 'hear' and respond to God’s warnings is indicative of His ongoing relationship with His people. Recognizing that God is the same yesterday, today, and forever (Hebrews 13:8), we must understand that His holiness and the consequences of sin do not change. Thus, the call to wake up and reflect on the state of our hearts remains crucial for all believers.
