Why is it important that Jesus does not pray for the world?

In John 17:9, Jesus clearly states, 'I pray for them; I pray not for the world, but for them which thou hast given me.' This highlights that His intercession is limited to the elect—those for whom He died and is now praying. This strengthens the assurance of salvation for believers, as it distinguishes between his effective intercession for His chosen and the general world. It emphasizes that His work is purposeful and directed towards securing the salvation of those specifically given to Him by the Father.
