How do we know that Christ's prayers help our faith?

In Luke 22:32, Jesus tells Peter, 'Satan has desired to sift you as wheat, but I have prayed for you, that your faith fail not.' This profound assurance reveals that the security of the believer does not rest on their strength but on Christ's interceding work. Regardless of our struggles, doubts, or offenses caused by trials, Christ's prayers safeguard our faith. Even in moments of deep uncertainty, when we feel most alone, we can rest in the truth that He actively intercedes on our behalf. His advocacy ensures that none of God's elect will ultimately be lost, demonstrating a preserving grace that shines even in the darkest of situations.
