As long as you're alive, the reconciliation with Allah is very quick and easy because He is waiting for you:

((Allah is happier with the repentance of His worshipper than the lost man who has found his way, more than the sterile woman who has been given a baby, and more than a thirsty man who has found the water.))

[Ibn 'Asaker in Amaleeh from Abu Hurayra]

 Again, I'll tell you the story of Bedouin who has ridden his camel, and his drink and food with him:

((Allah is happier with the repentance of His worshipper than a Bedouin was with his camel in a wilderness land, then the camel has escaped with his food and drink, and the man has despaired of finding it; then he came to a tree, and while he was lying down in its shade, he found his camel standing before him, so he held its bridle, and said rejoicingly: "O Allah, You're my worshipper, and I'm Your lord!!" He has committed a mistake because of his big joy.))

[Muslim from Anas ibn Malek]

 The heart of the Bedouin was right, and his tongue was wrong; so the Prophet, peace be upon him, said in his reliable speeches: "Allah is more happier with His penitent worshipper than the happiness of this Bedouin when he found his camel". So what are you waiting for?!!

(O My people who worship Me and who do not, who have carried disobedience to excess: do not despair of Allah's mercy; Allah forgives all sins; He is All-Forgiving (AL-)Gaffour) and the Merciful (AL-Rahim) (53)

[Al-Zumar]
