Why is it important for Christians to hear the gospel regularly?

Regularly hearing the gospel is vital for Christians because it reinforces the foundation of their faith, reminding them that their salvation is entirely of the Lord and not their own works. Luke 4 illustrates that Jesus preached the kingdom of God, showing us that continual exposure to His word is integral for spiritual growth and perseverance. The best place for any sinner and saint alike is under the preaching of the gospel, where they can experience Christ's power and learn to rely solely on His righteousness and grace.
