The Word of God is A Seed

So is My word that goes out from My mouth: It will not return to Me empty, but will accomplish what I desire
and achieve the purpose for which I sent it - Isa 55:11

This is the meaning of the parable: The seed is the Word of God - Luke 8:11

For you have been born again, not of perishable seed, but of imperishable, through the living and enduring Word of God - 1 Peter 1:23
