What does the Bible say about passing through waters and fire?

Isaiah 43:2 states, 'When thou passest through the waters, I will be with thee; and through the rivers, they shall not overflow thee: when thou walkest through the fire, thou shalt not be burned; neither shall the flame kindle upon thee.' This promise reminds believers that God is ever-present during trials and tribulations. Believers are assured of His presence and protection even in the face of severe challenges. In relation to Hebrews 11:29 where God's people passed through the Red Sea on dry land, we see a powerful testament to God's deliverance and the idea that every believer will encounter trials, but God's presence guarantees their safe passage.
