The Guarantee Of Their Eternal Future (John 14:1-3).
He commences by giving them the confidence that their eternal future is secure. Such a certainty would undergird any problems that might arise in the future, and enable them to face whatever came with equanimity. Certainty as to their destiny would go a long way to bolstering their faith in times of trouble.
At such times as this men of faith would normally turn the eyes of their followers away from themselves to God, especially if their death was imminent. They would point out to them that their lives were in the hands of God, and of God alone. It must be seen therefore as quite remarkable that Jesus, while certainly pointing them to God, laid the greatest emphasis on their looking to Himself.
