How do we know the promise of strength in Christ is true?

The truth of Philippians 4:13, which asserts that we can do all things through Christ's strength, is affirmed throughout Scripture. The experiences of biblical figures, like Paul, who faced persecution and trials yet remained steadfast in faith, attest to this promise. Furthermore, the testimony of countless believers throughout history who have relied on Christ's strength through various challenges provides tangible evidence of its truth. The assurance that God works in us both to will and to do for His good pleasure (Philippians 2:13) reflects His active presence and empowerment in our lives, enabling us to fulfill His calling.
