How do we know Christ is Lord over all?

The New Testament clearly affirms Christ's lordship, particularly in passages like Philippians 2:9-11, which states that God has exalted Him and given Him a name above every name. Jesus Christ is Lord of all people, events, and circumstances, with nothing happening outside of His will. His power over the forces of darkness and the assurance in Romans 8:31, 'If God is for us, who can be against us?', emphasizes His supreme authority. This lordship brings confidence to believers that their lives are under His sovereign guidance.
