In regards to "does not obey the Son" in the New American Standard translation of the Bible, this does not mean that receiving eternal life is received based on the merits of our obedience/works which follows believing on the Son, but obey by choosing to believe on the Son. If John wanted to make obedience the central theme in salvation here, he would have said: "He who believes and obeys the Son has eternal life," but that is not what John said. To obey the Son here is to believe on the Son.
The King James Version renders this same verse as: He that believeth on the Son hath everlasting life: and he that "believeth not the Son" shall not see life; but the wrath of God abideth on him. The NKJV says "does not believe the Son" and the NIV says "rejects the Son." The Greek word translated as "believeth not" in that verse is apeitheo and it means: not believe, disobedient, obey not, unbelieving. Strong’s definition of apeitheo is "to disbelieve willfully and perversely." In the context of 3:36, to not obey the Son means to reject His message by refusing to believe on the Son.
I have often heard works-salvationists (including Roman Catholics and Campbellites) cite John 3:36 in the NAS translation of the Bible and stress the word "obey" the Son, then write a blank check with the word "obey" and fill out whatever amount of works they feel are necessary to be saved (water baptism, partaking of the Lord's Supper during Mass, obeying the commandments, performing works of charity etc..) and call that believing on the Son, yet they are actually believing "in their works" and not IN/ON THE SON.
