How do we know Jesus Christ is Lord of all?

The declaration in Acts 10:36 that Jesus Christ is 'Lord of all' demonstrates His supreme authority as the God-man who reigns over the universe. This title conveys the truth that all power and judgment have been entrusted to Him by the Father (John 5:22-23). Peter's statement serves as a reminder that Jesus' lordship is not limited to any particular group or nation; rather, it encompasses all humanity. His lordship guarantees that He is capable of saving and justifying all who believe in Him (Acts 10:43). This is central to the gospel message, affirming that through Christ's redemptive work, believers can be assured of their salvation resting not on their merit, but on His finished work alone. His resurrection further validates His lordship, serving as the cornerstone of the Christian faith.
