ISLAM IS!!!Surrender
This is understood from a verse in the Holy Quran where Allah says:
"Inda deena inda lahi Islam." (Certainly, the only acceptable way which Allah will accept is Islam). [Holy Quran 3:19]
This submission requires a fully conscious and willing effort to submit to the one Almighty God ...Submission
"But no, by your Lord, they can have no Faith, until they make you (Muhammad, peace be upon him) as a judge in all disputes between them, and find no resistance against your decisions, and accept (the decisions) with full submission." [Holy Quran 4:65]
Total submission is required after the surrender and some terms have to be set forth by Allah to be understood by the Muslim. There can be no option in the matter as Allah says in another verse,
"It is not fitting for the believing man nor for the believing woman, that whenever Allah and His Messenger have decided any matter, that they should have any other opinion."
[Holy Quran 33:36]
Whatever Allah and His Messenger have set out as being the Way of Islam is incumbent on the believer, man or woman to follow completely. One must consciously and conscientiously give oneself to the service of Allah.....Sincerity & Purity of Intention

The heart must be clean and honest. Allah is Pure and He only accepts pure.

"Verily, deeds are rewarded by intention. And everyone will have the reward for that which he has intended."
[A saying of the Holy Prophet Muhammad, peace be upon him - Sahih Al-Bukhari Vol. 1 #1]

Sincere intention is the key to the success or failure of the Muslim. All that he or she does must be for the sake of Allah and not for the chance to show off or call attention to himself or herself. If there is even a speck of pride or showing off for the people instead of doing for Allah, then the whole of the matter will be rejected by Allah on the Day of Judgment. This is due to the fact that Allah wants purity of intention and purity in deed.
