So then in the world there are millions of Jews,Israelis ect. (most live in Israel or the U.S.) is what is written in their hearts the same as whats in yours?
Yes, but the Bible tells us our hearts can be hardened, perverted, weakened, etc.
The more someone violates their conscience (the law written on their hearts), the more hardened the heart becomes, the more easy it becomes to do the wrong thing.
That's why Paul says don't get drunk, be filled with the Holy Spirit.
(Eph 5:18) Do not get drunk on wine, which leads to debauchery. Instead, be filled with the Spirit,
