We must face the reality that we can only reach the reachable and teach the teachable. Some people are not receptive to the truth. We need the discernment to know the type of person we are dealing with (which comes through spiritual growth and experience). The apostle Paul did not unload the whole dispensational wagon on everybody that he talked to (1 Cor. 2:1-3:3).
We should only try to show people the mystery if we discern that they are sincerely walking in the light they have with a desire to learn more truth (e.g. Acts 18:24-26). It is important that we are motivated by charity and not pride as we try to teach others (2 Tim. 2:24-26). There was a time when we didn’t know this truth either (1 Cor. 4:7)!
Example of a conversation starter: Have you ever wondered why there are so many different denominations? How can so many groups, who all claim to believe the Bible, have so many different beliefs (1 Cor. 14:33)? They are trying to interpret the Bible instead of allowing the Bible to interpret itself (2 Pet. 1:20). The Bible is God’s word and therefore it must be studied God’s way. God did not start any denominations. He is only building one spiritual church (Eph. 4:4-6).
Example of how to introduce right division to someone: Did you know there is a verse that tells us exactly how to study the word of God (2 Tim. 2:15)? Notice that it does not say divide truth from error, but rightly divide the word of TRUTH. All scripture is the truth and is FOR us (2 Tim. 3:16), but it is not all written directly TO us. God never changes in His person and moral principles (Mal. 3:6), but He has changed in His dealings with man through the ages as He gave progressive revelation. If you don’t understand this, the Bible will be a confusing book to you.
We cannot possibly obey everything in the Bible. Consider the basic issue of what we are to eat:
Adam (Gen. 1:29) = no meat
Noah (about 1500 years later, Gen. 9:3-4) = meat with blood
Moses (about 1000 years later, Lev. 11:46-47) = clean meats
Paul (over 1500 years later, 1 Tim. 4:1-5) = nothing is to be refused (note to teach otherwise in this age is a doctrine of devils)
We must not try to invent our own divisions or ignore the ones God put in His word. Everybody divides the Bible (OT/NT), but we must rightly divide it.
Prophecy: SPOKEN since the world began (Acts 3:19-21)
Mystery: SECRET since the world began (Rom. 16:25)
The mystery of the Body of Christ was first revealed and made known through the apostle Paul (Eph. 3:1-13; Col. 1:24-27).
There is one family of God, but there is a difference between God’s earthly people and His heavenly people (Eph. 1:10; 3:15). If words have any meaning, there must be a difference between the nation of Israel who is destined to reign on the earth over the nations (Isa. 60:1-5) and the spiritual Body of Christ (neither Jew nor Gentile, Gal. 3:27-28) who is seated in heavenly places and is destined to reign there eternally (Eph. 2:6-7; Phil. 3:20; Col. 3:1-4).
