How can I be sure I'm saved as one of the Lord's sheep?

Certainty of salvation as one of the Lord's sheep comes not from our own efforts but from understanding and embracing God's grace. Ephesians 2:8-9 emphasizes that we are saved by grace through faith, not by our own works. This means our assurance is rooted in what Christ has done for us, rather than any merit of our own. We are encouraged to seek confirmation of our faith by observing our response to Christ's voice, our desire to follow Him, and our love for God, knowing that He first loved us. Thus, our focus should be on Him, the Good Shepherd, rather than our doubts.
