"All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness: (17) That the man of God may be perfect, thoroughly furnished unto all good works." (2 Timothy 3:16-17)
"These were more noble than those in Thessalonica, in that they received the word with all readiness of mind, and searched the scriptures daily, whether those things were so." (Acts 17:11)
Jesus warned His disciples to be careful! Do not allow anyone to deceive you (Matthew 24:4.) He also told them that people must live on every Word from the mouth of God (Matthew 4:4.)
Thus it is critical for believers to understand 2 Timothy 3:16-17 quoted above!
Words of caution:
* Many people will reference Bible verses, and then tell you what they mean. This is essentially teaching. However, if a person's interpretation of the Scripture dramatically changes the clear meaning of the verses... BE WARE!
Understanding the Bible is very important. Making the Bible say the opposite of what it clearly states is ungodly and very dangerous.
* Often, false teachers will claim that the Holy Spirit has led them to their understanding. The Holy Spirit has written all of the Bible (via men) and is not at all intimidated by the Scriptures. As a matter of fact, the Holy Spirit commends the Bereans (see Acts 17:11 quoted above) for testing the Apostle Paul's teaching against the Scriptures!
Thus, the Holy Spirit sent the Apostle Paul to preach and teach...then the Holy Spirit applauds the Bereans for testing the message that the Holy Spirit gave Paul against the Bible! (Now that is something to try and wrap your mind around!)
Bottom line: Develop and understand your beliefs based solely on the Bible. Test the doctrines and teachings of all others solely with the Word of God.
Do not tenaciously adhere to what you have been taught or have believed over the Scriptures.
Eisegesis: Do NOT perform eisegesis (forcing the Bible to say what you WANT it to say.)
Exegesis: DO study the Bible exegetically (believing what the Bible actually says, whether you like it or agree with it.)
God desires us to have sound doctrine...more than we desire it. If we remain faithful to solid Bible study principles, relying on the Holy Spirit to guide us, we can confidently arrive at, and defend accurate Bible doctrines.
