If one is devoted to only one form of God, does that mean we are disrespecting other forms of God? No, that could only be true if God were many. God is not many. Even though there are many religions on earth, God is still one.
In other countries, in other traditions, people may call the ultimate Divine power as God, Allah, Bhagwan, Ishwar, Khuda. There are many names, but God is one. People may be living at different places on the globe and worshiping God in different ways, but God cannot be two. Even if there are souls residing at other places in this universe, it's the same God for them, as we have over here. What to say of different countries and religions and traditions on this one tiny little earth planet? But that supreme God has unlimited forms, unlimited powers, and those powers are revealed and concealed according to the situation and according to what type of bliss God is giving. This is why God has so many Divine forms, unlimited forms, but God is only one.
Yesterday I explained a type of structure to help you understand using a spectrum. God can be formless, God can also be almighty, and God can also be loving. So on one hand, we have on one end of the spectrum, we have complete lovingness, and on the other end of the spectrum we have complete almightiness, and in both cases the other is not present, not revealed. Where ultimate lovingness is revealed, God's almightiness is concealed or subsided or merged into that lovingness. And where the lovingness is completely concealed, God's almightiness takes priority. God's almightiness is revealed in totality. And to the extent His lovingness starts to be revealed, to that same extent the almightiness becomes hidden. Like when the moon is in the sky, but then the sun begins to rise the moon may be full and bright, but as the sun comes up, the moon's light doesn't reduce. It starts to merge into the light of the sun.
This is what happens with God's almightiness. As His lovingness begins to shine, that almightiness becomes negligible, insignificant, even though it's still there. And it's for this reason that God behaves differently and represents Himself in different forms.
