Why is hearing God's voice important for Christians?

The importance of hearing God's voice is highlighted in Hebrews 3:7, where it states, 'Today, if you will hear His voice, harden not your hearts.' This hearing is not simply auditory but indicates an active faith that responds to God's Word. The sermon argues that Christians need to rely on fresh supplies of God's Word daily, just as one needs daily nourishment. Believers are encouraged to come together to hear the preached Word, as it is the means by which God communicates His grace and guidance, helping them resist unbelief and remain steadfast in their faith.
