The worshippers are like warriors -Hadith:
Abu Huraira رضي الله ﺗﻌﺎﻟﯽٰ عنه
narrated that Allah's Messenger ﺻﻠﯽ الله ﺗﻌﺎﻟﯽٰ ﻋﻠﯿﮧ ﻭﺍٓﻟﮧ ﻭﺳﻠﻢ said,
"Shall I not tell you of something by which Allah erases sins and elevates ranks?"
They (the sahabah) said, 'Of course, 0 Messenger of Allah!"
"To perfect ablution even in trying conditions, to go towards mosques very often and to wait for the next salah after offering one. This is ribat (guarding the frontiers of Islamic lands)."
[Bukhari 7733, Muslim 251, Nasai 90]
Those who neglect and belittle the acts of perfecting one's Ibadaat and think that only political activitism is the 'be all and end all' of Islam should read the Quran and books of Hadeeth properly.
Every thing has it's place in the Deen and a strong spiritual relationship between an individual and his Lord is central to the Islamic world view. All other injunctions of Islam are meant to protect and improve this relationship.
Also we should not forget that the success in the other areas of the Deen depends on perfecting this spiritual core. The entire Seerah and the lives of the Sahaba and the Salaf bear ample testimony to this.
