Do you need to read the law written in ink in the bible to know what that law is? Not according to one sda member in the thread sda, nor according to Paul:
Indeed, when Gentiles, who do not have the law, do by nature things required by the law, they are a law for themselves, even though they do not have the law. 15 They show that the requirements of the law are written on their hearts Rom2:14&15
I know these scriptures quite well. You need to add the context first however and read them in light of both ROMANS 2 and ROMANS 3. The context scriptures here is that both JEWS and GENTILES are all under sin there is none rightoeus no not one. The context scriptures are..
ROMAN 2:11-13
[11], For there is no respect of persons with God.
[12], For as many as have sinned without law shall also perish without law: and as many as have sinned in the law shall be judged by the law;
[13], For not the hearers of the law are just before God, but the doers of the law shall be justified.
PAUL goes on to make this clearer in ROMANS 3
ROMANS 3:19-20
[19], Now we know that whatsoever things the law says, it says to them who are
under the law: that
every mouth may be stopped, and
all the world may become guilty before God. [20], Therefore by the deeds of the law there shall no flesh be justified in his sight:
for by the law is the knowledge of sin.
Paul is saying in these two chapter that none are righteous 3v10 This includes both JEW and GENTILE 3v9.
Now coming back to ROMANS 2:14-15
[14], For when the Gentiles, who have not the law, do by nature the things contained in the law, these, having not the law, are a law unto themselves:
[15], Who show the work of the law written in their hearts, their conscience also bearing witness, and their thoughts the mean while accusing or else excusing one another.
Paul is using the example of how God's law is kept and that is having the law written in the heart through love. It is not saying that God's LAW does not give us a knowledge of what sin is and it does not say that Gentiles obey God's LAW without God's WORD because PAUL says all have sinned all are guity before God and God's LAW gives us a knowledge of what sin is *ROMANS 3:9-10; 19-20 and as the scriptures that show the context say...
ROMAN 2:11-13
[11], For there is no respect of persons with God.
[12], For as many as have sinned without law shall also perish without law: and as many as have sinned in the law shall be judged by the law;
[13], For not the hearers of the law are just before God, but the doers of the law shall be justified.
Hope this is helpful
