How do we know Christ strengthens believers?

The promise of Christ strengthening His followers is grounded in scripture. Philippians 4:13 states, 'I can do all things through Christ which strengtheneth me,' establishing that our ability to navigate life's challenges is innately tied to Jesus's empowerment. This strength is not merely physical but encompasses spiritual fortitude, helping believers encounter various trials with a sense of peace and contentment—a contentment rooted in the assurance that God is always in control. Furthermore, Isaiah 40:29 reassures us that the Lord gives power to the faint and increases strength to those who have no might, exemplifying His faithful provision for all believers in every circumstance.
