There are way too many assumptions and assertions and not enough proving it by the Scriptures. There is even the bold assertion that we don’t need book, chapter, and verse for what we say or do in religion. They say, the spirit of the law is all that counts. I can’t even imagine equating the words of men with the Word of God. Error gives no proof, neither seeks it, “for every one that does evil hates the light, neither comes to the light, lest his deeds should be reproved” (Jn. 3:20).
The Bible commands that when we speak in religious matters, as if anything else matters, we speak only what God has spoken. “If any man speak, let him speak as the oracles (the very words) of God” (1 Pet. 4:11). If there is not an oracle of God to back up what one says about a certain subject, then you can mark it down, that doctrine came from man, not God. Can one say that one has “spoken as the oracles of God” when all that is heard are jokes and anecdotes ? Paul said, “Preach God’s Word” (2 Tim. 4:2), not to entertain the with “Man’s words”.
In order to be pleasing to God, one must have faith, for “without faith it is impossible to please him” (Heb. 11:6). Where does one get this faith? “So then faith comes by hearing, and hearing by the Word of God” (Rom. 10: 17). But, one cannot be said to have faith if he does not possess the “Spirit of faith” as spoken of by Paul in 2 Corinthians 4:13. “We having the same spirit of faith, according as it is written, I believed, and therefore have I spoken; we also believe, and therefore speak.” So then it takes hearing, believing, and speaking the Word of God to have the same kind of faith which pleases God. If we hear, believe and speak things which are not found in the Word of God, then we posses a faith which is foreign to the scripture and is displeasing to God.
Not only must we prove our doctrines by the Bible, but we must have biblical authority for what we practice. Jesus told the Devil “that man shall not live by bread alone, but by every Word of God” (Lk. 4:4). The apostle John taught the same thing when he said, “Whosoever transgresses and abides not in the doctrine of Christ, has not God. He that abides in the doctrine of Christ, he has both the Father and the Son” (2 Jn. 9). If we live by, or abide in, something which is not found in Scripture, then we don’t have God. If we do something in religion, then we must prove it by the Word of God. Otherwise, it is a faithless act. Whatsoever is not of faith is sin (Rom 14:23).
The Bible also commands us to follow the example of those who taught and practiced only what God said. “Those things, which ye have both learned, and received, and heard, and seen in me, do” (Phil. 4:9). What do we see that Paul did? “And Paul . . . reasoned with them out of the Scriptures” (Acts 17:2). He didn’t just assert that Jesus was the Christ, he proved it to the Jews with Scripture. Apollos did the same by “Showing by the scriptures that Jesus was Christ” (Acts 18:28). Let us “follow” their example (1 Cor. 11:1).
“All scripture . . . is profitable for doctrine for reproof, for correction, for instruction in righteousness: that the man of God may be perfect, thoroughly furnished unto all good works” (2 Tim. 3:16-17). Any thing that we would ever need to believe or do to be pleasing to God can be found in the Bible. Be sure that you can “Show by the scriptures” everything that you believe, teach, and do, because if you cannot, it’s worthless!
Faith only is a doctrine of man and not of God (Jam 2:24). Once saved, always saved is a doctrine of man and not of God (Gal 5:4) . Infant baptism is a doctrine of man and not of God (Acts 8:35-39). Instrumental music in praise to God is a doctrine of man and not of God (Eph 5:19). These doctrines were not refuted with man’s opinion but with God’s Word. If we desire God’s heavenly reward, then we must prove all things by God’s Word and hold firm that which is good (1 Thess 5:21). “And be not conformed to this world: but be transformed by the renewing of your mind, that you may PROVE what is that GOOD, and acceptable, and perfect, Will of God” (Rom 12:2).
