“Peace I leave with you, my peace I give to you. It is not as the world gives that I give to you”.
Jesus now assures them of peace in mind and heart, which He will give to them, indeed is now giving to them. His Spirit will not only teach them but will give them peace within, ‘peace that passes all understanding' (Philippians 4:7), a part of the fruit of the Spirit (Galatians 5:22). It is a peace which is permanent, not dependent on the vicissitudes of the world. It is a peace that nothing can touch (except deliberate sin). The one who enjoys this peace may be troubled, as Jesus was sometimes troubled, but he will have an inner certainty beneath that makes the troubles bearable and temporary. For it His peace, a peace that they enjoy because of His presence within them, and through an awareness of the greatness of God's love for them (Ephesians 3:17-19).
