No one comes to the father but through me

Jesus said to him, "I am the way, and the truth, and the life; no one comes to the father but through me." (Jn 14:6)

What does John 14:6 mean? Does it contradict Romans 2:12-16?

For all who have sinned without the Law will also perish without the Law, and all who have sinned under the Law will be judged by the Law; for it is not the hearers of the Law who are just before God, but the doers of the Law will be justified. For when Gentiles who do not have the Law do instinctively the things of the Law, these, not having the Law, are a law to themselves, in that they show the work of the Law written in their hearts, their conscience bearing witness and their thoughts alternately accusing or else defending them, on the day when, according to my gospel, God will judge the secrets of men through Christ Jesus. (Rom 2:12-16)


Maybe God will look at everyone (believers or non-believers) by what they do, because what they do reveal what they believe. In the end, it is still Jesus Christ who judges (no one comes to the Father but through Me). It might not mean to be saved we must become Christian, but it certainly is one of the surest way.
