Being a true christian the first priority is to love the Lord our God with all your heart, and with all thy soul, and with all thy mind, and with all thy strength. I have been an NRI almost 30 years since i started working and then doing own small business. I was with my family and later become widower. No culture or mingling with different kind of people did not make any difference in me since God has protected me from all kind of ungodly and unwanted things.What is born of flesh is flesh and what is born of Spirit is Spirit. When we born of spirit then it is the responsibility of God to protect us from ungodly things and circumstances and we have to obey our heart and it is the temple of God of those who are born of spirit. When born of spirit we feel like we are a citizen of heaven and whatever earthly will not make any change in us. We have to think of heaven and one who dwells in it.
