What does the Bible say about Christ preserving us?

In John 10, Jesus describes Himself as the Good Shepherd who knows His sheep and assures us that no one can snatch them from His hand. This eternal security emphasizes that our salvation is fully dependent on Christ's ability to keep us. Paul affirms this in 2 Timothy 1:12, stating his confidence in God's power to guard what has been entrusted to Him until that day. Thus, the assurance of preservation in faith is not conditioned on our ability, but rather on Christ's unchanging promise.
