Believeth Not or Not Obey?
The Legacy Standard Bible butchers John 3:36 by changing "BELIEVETH NOT" to "NOT OBEY".
(LSB) He who believes in the Son has eternal life; but he who does not obey the Son will not see life, but the wrath of God abides on him.
Not only is it obvious that "believing" and "obeying" are 2 different things. The Legacy Standard Bible would try to convince you that they are by providing a footnote next to the word "obey", that reads: "or believe".
Shoddy work, if you ask me.
It's also obvious to most Christians that the keyword in the book of John is the word "believe". It shows up over 100 times in the following forms: "believe, believed, believest, believeth".
Furthermore, John is a great book of the Bible to show unbelievers the importance of believing on and in the Lord Jesus Christ as God. Christian's are born-again BELIEVER's, they are not a born-again OBEYER's.
Believers should absolutely desire to obey God after they are saved. However, a believers' assurance of salvation doesn't come from their ability to obey. If it did, no one could be assured of their salvation, because no believer 100% obeys the Lord.
If you build the doctrine of justification based off of someone's sanctification, you end up with confidence in good works, rather than confidence in Christ as your basis for assurance of salvation.
The Bible is clear that you can be fully assured of your salvation by your BELIEF, not your OBEDIENCE.
1 John 5:13 These things have I written unto you that believe on the name of the Son of God; that ye may know that ye have eternal life, and that ye may believe on the name of the Son of God.
Here's what the Bible actually says in John 3:36...
(KJV) 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.
