What does the Bible say about God's house being a house of prayer for all people?

In Isaiah 56:7, God declares, 'Mine house shall be called a house of prayer for all people.' This phrase reveals God's intention to create a community that transcends ethnic and social barriers. The context highlights that both the elect Jews and Gentiles are welcomed into His presence through faith in Christ, indicating that worship is not limited to a certain group but is accessible to all who believe. This inclusivity is foundational for understanding God’s grace as it invites everyone, regardless of background or status, to approach Him in prayer, trusting His mercy and salvation.
