 right that Allah subhanahu wa ta'ala has over us can never be fulfilled by our striving. And therefore Allah ta'ala enters us into jannah based on His mercy not our actions. And when the Prophet sallallahu alayhi wasallam informed his companions of this, they said to him wa la enta ya rasulullah, ya rasulallah, not even you, O messenger of Allah, not even you will enter jannah based on your actions. He said not even me, I will only enter if Allah envelops me in His mercy and His grace.
