How do we know faith is the answer to heart trouble?

The sermon explains that faith acts as the cure for heart trouble, as seen in the words of Christ where He urges His disciples to believe in Him just as they believe in God. This faith is not mere belief in existence but a deep trust in God's plan and providence, which encompasses all aspects of life. Faith allows us to confront fears and anxieties rooted in the uncertainties of life with the assurance that God governs every situation according to His perfect will. Thus, embracing faith helps alleviate our troubled hearts, reminding us of our identity in Christ and His redemptive work, ultimately leading us to trust Him in all circumstances.
