How do we know that God's grace is sufficient for our struggles?

The sermon illustrates that God's grace is always sufficient, especially for believers facing trials. Paul reassures Timothy that although he suffers in prison, he is confident that God is capable of preserving him and those who trust in Him. This is echoed in the assurance that Christians can face suffering without shame when their hope is in Christ. The grace of God empowers believers not to cower in fear but to confront challenges with power, love, and self-discipline, as it provides the inner strength needed to endure hardships. This truth is foundational in affirming that Christians possess the resources to navigate their sufferings, grounded in their identity and relationship with Christ.
