Ibn al-Qayyim says,

Get up and hurry in servitude to Allah and being with Him in the Home of Peace, without any tiredness, hardship or fatigue but by the nearest and easiest of paths. And this is by realizing that you are in a time between two times which is what constitutes your life, and this is the present time which is between what has passed and what is yet to come. Then that which has passed you can correct by repentance, remorse and seeking forgiveness. This is something in which there will be no tiredness, fatigue or any straining efforts required on your behalf.It is nothing but the action of the heart…And there is due from the servant to Allah, in every moment from his time, servitude which will advance him or bring him near to Allah. So if he spend his time in servitude to Allah, he will come closer to his lord and if he busies himself with desires or relaxation or inactivity, he will lag behind. And the servant never ceases either to be moving forward or falling behind and there is no stopping whilst on the path, ever.
