How do we know that Christ chooses His disciples?

In John 13:18, Christ explicitly states, 'I know whom I have chosen,' highlighting His perfect and sovereign knowledge of all His followers. This assures believers of their secure position in Him, emphasizing that their acceptance and faith are not a product of human merit but a result of Christ's divine selection. Such a truth serves both as a warning to the unrepentant and comfort to the genuine disciples who may face misunderstanding or persecution. Ultimately, the sovereignty of Christ in choosing His disciples underscores the grace that governs their faith and the assurance of His transformative power at work in their lives.
