Hi ShemTov,
I am new to the forum as well.
I would say that the garden is one’s mind, which we must cultivate and plant that which we want to grow, which fruit we want to bring forth. The mind is a battle field or a well tended garden.
In scripture house or household is also used to describe one’s house (upper room often appears in scripture as well as the members of one’s household).
City of God is where God dwells and for myself, as God’s temple, that is within me (and every person). But I think in scripture it also tends to refer to a certain level of consciousness and creativity.
