No brother, stand is not equal to being obedient. Heavens and Earth are physically standing as physical entities because of the Command (Amr) of God. This is the meaning of the first part of 30:25. Link this with the second part of 30:25 and you would see that it is informing us that when God issues a call for us we will also be following His commands and get out of the earth.
30:26 is simply stating that at the end (the final day) nothing has any choice but obedience to Him through His call/command. It has a beautiful message for us, i.e. we only have some limited choice during this life. Once this life is over, we have returned to Him, His command will bring us back and we would not have any choice but to obey as do other things.
