We worship the God of Abraham, Moses, Jesus , Muhammed … The God of All creations… the God that revealed the Torah , The Gospel and the Quran
An interesting claim, in light of the common contention among Muslims that the previous two books have been corrupted. But I digress…
We don’t worship a moon God. This is a Popular Christian myth about muslims.
It really is most unfortunate and irksome, isn’t it? Although we obviously will never see eye to eye on many things, I am always quite unhappy when I see Christians repeating this idea (as well as other, also ridiculous ideas, such as the “number of the beast” being graphically similar to “Allah” via a Greek cipher or some such nonsense that was peddled by Walid Shoebat some time ago, and eagerly parroted by some here; blah).
I understand God as one with no forms, states , parts or trinity.
This is not the place to get into any length debate over such things, but it is worth repeating in the face of probably some questionable explanations you may have gotten elsewhere that traditional Christian theology does not speak of the Holy Trinity as “parts” or “states”. Depending on the context, you may have been looking at something very influenced by Sabellianism, as many Christian-identifying sects are these days. But this thinking is modalism through and through, and is a heresy, condemned (if I recall correctly) at the first Council of Constantinople in 381 AD.
The names are actually not important.
Then why do you have 99 of them in your religion?

(Kidding, of course!)
There are people who can’t speak still picturing the God you worship in your head is enough.
I am curious to hear about how you square this with your own belief that God is formless, as you mentioned above. You picture God in your head, but God has no form, so…?

At any rate, this is one area where Orthodox Christians and Catholics definitely differ, as Catholics are encouraged (via historical precedents set by their saints like Ignatius of Loyola, founder of the Jesuits) to actively imagine things during their prayer, but this is not encouraged in Orthodoxy. When we pray, all of our soul, mind, heart, and body is to be engaged in the act of worship and supplication, not in imagining this or that image or shape or event. It can be tough, but God (or too much TV as a youngster) blessed me with a terrible imagination, so it’s not so difficult to get used to once you’re in the act of prayer and supplication.
Call him Allah , YHVH Yahoo. The merciful … it doesn’t matter as long as you know who he is in your heart.
A noble sentiment, indeed. We do indeed affirm His mercy, which endures forever, and His transcendence and Lordship over all creation.
