How do we know that faith must be proven?

The evidence of proven faith can be seen in how God interacts with His people throughout Scripture. In John 6, Christ asked Philip a question not because He was unsure, but to demonstrate God's sovereign knowledge of the situation. God's approach showcases that He often brings His people to the end of their resources to usher them into a deeper reliance on Him. It’s through these trials that we, too, can affirm our trust in a sovereign God who knows what He will do, which reassures us of His unchanging capability and character in responding to our needs.
