How do we know that God's grace sustains us through trials?

Paul's trials serve as a testament to the sustaining power of Christ’s grace in the lives of believers. He emphasizes in his letters that he does not glory in his own abilities or righteousness but rather in the power of Christ that upholds him through hardships. This is beautifully encapsulated in 2 Timothy 4:16-17, where Paul acknowledges that despite being forsaken, the Lord stood by him and gave him strength. Such experiences affirm that God’s grace is sufficient for our struggles, allowing us to endure and grow in our faith amidst difficulties.
