What is the way to feel faith, have prayers answered, and gain God’s love, despite being committed to acts of worship and refraining from major sins and disobedience to parents?

There are ways to increase faith and the love of Allah. Ibn al-Qayyim mentioned ten reasons that attract the love of Allah: reading the Qur’an, drawing closer to Allah through supererogatory acts of worship (nawafil), constant remembrance of Allah, preferring what Allah loves, contemplating Allah's names and attributes, witnessing His benevolence and kindness, the heart's humility before Him, private communion with Him and supplication during times of responsiveness, sitting with the righteous, and shunning everything that comes between the heart and Allah.
