How can you attain love of an infinite G‑d? Through love of your fellow human beings.
As Rabbi Chanina ben Dosa would say, “If people like you, G‑d likes you too.”
How did he know?
Because he knew that if people truly like you, it must be that you genuinely like them.
And when you hold genuine love in your heart for all people, inevitably you will come to genuine love for G‑d.
And those who love G‑d are loved by G‑d.
Hayom Yom, 6 Tishrei.
