We can know our faith won't fail because Christ intercedes for us and has given us the gift of faith (Luke 22:32).
Our assurance that our faith will not fail rests solely on Christ's intercession and the nature of true faith. In Luke 22:32, Jesus tells Peter that He has prayed that his faith may not fail. This indicates that the strength of our faith is maintained by Christ Himself, not our human effort. Genuine faith may waver through trials and tribulations, but Christ's promise is that He will uphold those He has redeemed. His work on the cross guarantees both our justification and the continuation of our faith journey. Even when we stumble, as seen with the apostles, those who are truly in Christ will ultimately persevere to the end because He is the author and finisher of our faith (Hebrews 12:2).
