How can I remain steadfast and strengthen my Taqwa while living in an environment where my own family and the people I live with take part in Haram actions even though our society is predominantly Muslim?
Bismillah
Thank you for your question. God-consciousness is a spiritual state which arises from the recognition of God within a person's being. As such God-consciousness is individual. It is true that if many individuals in a society are God-conscious then the society as a whole will benefit, but godly individuals have rarely had the luxury of such an environment.
The way to strengthen God-consciousness is through useful knowledge and action, trust in God, and a positive outlook in all that concerns Him. Taking time to reflect on how to build your relationship with God and the Infallibles (as) and continually taking positive steps towards that goal.
May you always be successful.
