In Matthew 19:24, this signifies spiritual truth by which one enters into life when it is lived. (Heaven and Hell 365[3])

636. 'I will destroy them together with the earth' means that the human race would perish together with the Church. This is clear from the fact that here the phrase 'together with the earth' is used. In fact, as previously stated, 'earth' in a broad sense means love and so the celestial things of the Church. Here because no love, nor anything celestial, was left it means self-love and that which is contrary to the celestial aspect of the Church. Despite this the member of the Church still existed because he possessed doctrinal matters concerning faith. For as has been stated, love includes faith within itself, and faith includes cognitions of faith, just as the earth includes the ground, and the ground includes the field.
