How do we preserve, grow, and multiply our good deeds, and reduce sins?

A Muslim must pay attention to this noble objective by: Fully observing the obligatory acts, then committing to the regular supererogatory acts, gradually increasing them, while striving against the self. And avoiding sins, and being mindful of God's awareness. And seeking help through encouragement and deterrence, and the company of righteous people. Finally, seeking refuge in Allah the Almighty and resorting to Him and supplicating to Him with truthfulness and sincerity.
