How do we know that God can perform miracles?

Scriptural accounts of God's actions, such as the parting of the Red Sea and the feeding of the Israelites in the wilderness, serve as clear evidence of His miraculous power. In Genesis 18:14, God asks, 'Is anything too hard for the Lord?' This rhetorical question emphasizes that God's sovereignty allows Him to operate outside the bounds of nature and human expectation, affirming the belief that He is actively involved in the world through miracles. Every instance of divine intervention in history is a testimony to His capabilities.
