I prefer the simple approach..:)
Jesus said:-"You diligently study the Scriptures because you think that by them you possess eternal life. These are the Scriptures that testify about me, yet you refuse to come to me to have life." (John 5:39/40)
First, you are proving your belief by using the Bible and not some outside extra biblical source.
Second, Jesus also said, “He that rejecteth me, and receiveth not my words, hath one that judgeth him: the word that I have spoken, the same shall judge him in the last day.” (John 12:48). In other words, Jesus said if we do not receive His words, those words will judge us on the last day. The words of Jesus we do have are now immortalized into Scripture. So to attack Scripture (saying they should not be studied as a means of eternal life) means one can say the same thing about the words of Jesus (Which is obviously false).
Three, 2 Timothy 2:15 says study to show yourself approved unto God, a workman that needs not be ashamed. God’s people are destroyed for lack of knowledge. 2 Timothy 3:16-17 says all Scripture is profitable for doctrine, correction, and instruction in righteousness that the man of God may be perfect unto all good works. Jesus says my words are spirit (spiritual), and they are life (John 6:63). Again, the words of Jesus are provided for us as Scripture, and so to attack Scripture and say they don’t bring everlasting life would be false because Jesus says His words are life. In fact…
Christ quotes Scripture as an authority:
In all Jesus' teachings He referred to the divine authority of the Old Testament (
Matthew 5:17-18;
Matthew 8:17;
Matthew 12:40-42;
Luke 4:18-21;
Luke 10:25-28;
Luke 15:29-31;
Luke 17:32;
Luke 24:25-45;
John 5:39-47). He quoted the Old Testament 78 times, the Pentateuch alone 26 times. He quoted from Genesis, Exodus, Leviticus, Deuteronomy, Psalms, Proverbs, Isaiah, Jeremiah, Ezekiel, Daniel, Hosea, Amos, Jonah, Micah, and Malachi. He referred to the Old Testament as “The Scriptures,” “the word of God,” and “the wisdom of God.” Jesus defeated the devil by using Scripture. For three words, "It is written" was said 3 times by Jesus in
Matthew 4:1-11. This is confirmed by
Ephesians 6 with how the Sword of the Spirit is the Word of God which is a part of putting on the amor of God so that one can stand against the wiles of the devil (
Ephesians 6:11,
16). For the Living Word (Jesus) is like a two edged sword that divides asunder the soul and the spirit because He always speaks the words of God because He is God (
Hebrews 4:12).
So in John 5:39-40: Jesus was not referring to how it was wrong for the Jews to regard the Scriptures as a means of eternal life.
For we know that by the word, it can quicken or make one alive (
Psalms 119:50).
Peter said to Jesus that he had the words of everlasting life, and yet Jesus quoted the Scripture of truth.
So in John 5:39-40: Obviously Jesus was referring to the fact about how the Jews missed in seeing Jesus in the Scriptures because they testified of Him who is eternal life. Jesus was not saying that it was wrong to seek the Scriptures for eternal life. He was criticizing how it would be wrong to do that if they missed seeing Him who is eternal life.
You said:
Paul said - "I'm worried lest you be led astray from the simplicity of Christ" (2 Corinthians 11:3)
The simplicity in Christ is being contrasted with those who preach another Jesus, and another gospel (2 Corinthians 11:4). The simplicity in Christ is being contrasted to false apostles, deceitful workers, transforming themselves [falsely] into the apostles of Christ (2 Corinthians 11:13). I believe they are the kind of believers who justify sin and evil and they can be found in great number in popular Christianity today. They believe they can sin and still be saved all because they have a belief alone in Jesus.
2 Corinthians 11:3 says,
“as the serpent beguiled Eve through his subtilty”
Simplicity is defined in the King James Bible Dictionary as:
freedom from duplicity; plainness. freedom from subtilty.
Source:
King James Bible Dictionary - Reference List - Simplicity
The devil employed duplicity. Duplicity is deceitfulness. Appearing to be one way as good, and yet having evil intentions. When the serpent tempted Eve in the garden, he told a truth to a certain point that would benefit him, and yet he also wrapped it up in a lie. The serpent basically told Eve a lie that she could break God’s command and not die.
So the simplicity in Christ is not referring to how you should be simple minded as we would understand that word today (like over simplifying things in life), but it would be in reference to being free from duplicity or deception or subtlety that the devil employed.
Simplicity is an archaic word in the King James Bible.
With the exception of CEV, most all the creators behind Modern Bibles have not picked up on this fact.
The Contempoary English Version best describes 2 Corinthians 11:3 in my humble opinion (using the words “
honest and sincere way” as a definition for the archaic word “
simplicity” in the King James Bible).
2 Corinthians 11:3 CEV says:
“But now I fear that you will be tricked, just as Eve was tricked by that lying snake. I am afraid that you might stop thinking about Christ in an honest and sincere way.”
So the CEV Translation describes best what the King James Bible is saying in this instance. Simplicity would mean honesty and or sincerity.
