As-Salaam alaikum,
Says Allah, Jallah-Jalalahu, in a Hadith Qudsi:---

"I am as My Servant thinks I am,
I am with him whenever he remembers Me; if he thinks of Me,
I think of him; if he mentions Me in a gathering, I mention him in
a gathering even better than it.

If he draws near Me a hand's span, I draw near to him in an arm's
length; if he draws to Me an arm's length, I draw closer to him by 2
arms length; and if he comes to Me walking, I go to him running." [Bukhari and Muslim].

This Noble Hadith tells us of the speed at which Allah Ta'ala changes a person's reality as He remembers Him. Because Allah has no need of/to travel, He does not have a body and isn't in creation, when He says "I go to him running", this refers to shaping man's perception of Allah, meaning 'I shape his reality quickly'. The more a person comes to Allah by Remembering Him (by various forms of Zikr), the faster Allah changes his perception towards good.

In this connection, the Prophet, Sallallahu alaihi Wasallam, said: IHSAN (human perfection) is to worship Allah as if you see Him, which is the highest form of worship. And in the Holy Qur'an, we have read it that:--

"He is with you, wherever you are" (57:4)
"And We are nearer to him than his jagular vein" (50:16)
