What does it mean that Christ keeps His people?

In John 17:12, Jesus affirms, 'I have kept them, and none of them is lost but the son of perdition.' This verse underscores the security of the believer, emphasizing that those whom the Father has given to Christ are preserved through His power. This assurance stems from the belief that genuine believers cannot be snatched from Christ's hand, reflecting the eternal security promised in Scripture. It highlights God's sovereign grace in the salvation of His people, instilling hope and confidence in their relationship with Christ.
