Yes. Paul was emphatic about that. He explained, “Even when Gentiles, who do not have God’s written law, instinctively follow what the law says, they show that in their hearts they know right from wrong.” (NLT, Romans 2:14) He continued, “They show that what the law requires is written on their hearts, to which their own conscience also bears witness; and their conflicting thoughts will accuse or perhaps excuse them on the day when, according to my gospel, God, through Jesus Christ, will judge the secret thoughts of all.” (NRSV, Romans 2:15–16)

Besides, as Paul pointed out, there was “no distinction between Jew and Greek; the same Lord is Lord of all and is generous to all who call on him.” (NRSV, Romans 10:12)
