Claiming Divine Revelation has been the mainstay of religious hucksters for thousands of years. The best advice is to avoid anyone who claims that God or some angel spoke to them. It’s well documented that when Joseph Smith’s wife caught him in adultery, he told her that God had revealed to him to allow or bring back polygamous marriages.
Some of the worst monsters in history have claimed direct communication with God. Preachers who claim divine revelation, especially where money is concerned, should be avoided like the plague. Claiming some kind of superior relationship or special communication with God that only he or she is privy to is the mark of a liar. The bible is clear that God ended personal communication and revelation with human beings with Jesus Christ:
In the past God spoke to our forefathers through the prophets at many times and in various ways, but in these last days he has spoken to us by his Son. (Heb 1:1-2)
Notice the past tense: “has spoken to us,” not “is speaking to us.” God didn’t somehow forget to add something to the Bible, and now has to speak to someone directly. No one has a secret phone line to the Throne. Jesus told the apostles that the Holy Spirit would provide “all truth.” (John 16:13) The idea that God reveals himself to folks for specific purposes has no scriptural support whatsoever. Those to whom He did speak were pertinent to His Divine Will guiding history toward the birth of Jesus Christ. Claiming God “told me to marry so-and-so” doesn't square with scriptural precedence.
Everything God has revealed to mankind has been laid out in His Last Will and Testament—the New Testament. He doesn’t tell people to sell their homes and donate the money to the church. He doesn’t “lay it on your heart” to abandon your job and family and head off to the foreign mission fields. Many who listened to their own conscience, claiming it was God speaking to them, have met misery and failure as a result. Others who have had overwhelming success in such endeavors did so because they were done with much prayer, advice from others, and a good church to back them up.
Who said it was God whispering in your ear? What proof do you have? It could very well be Satan, who disguises himself as an angel of light. (2 Cor 11:15) Even if you’re a Christian, does that make every thought that enters your mind from God? Or is it just the ones you think are His?
A person can by led by the Spirit (Rom 8:14; Gal 5:18), but this is gained through prayer, study, and application of what they learn from the Word. Being led by the Spirit doesn’t mean direct and detailed conversation with God.
I was listening to a Christian radio broadcast one day, and a young lady called in. She had planned to marry someone in the church. However, her plans were put on hold when someone in her church claiming the gift of discernment said that God had revealed to him that she must not marry that person. She was calling the radio host to get his thoughts. She had doubts and concerns. The person running the radio show started hedging his bets, telling her that she should probably listen to the person. After all, he has the gift of discernment.
Since the apostles were the only ones who could dispense miraculous gifts, (Acts 8:18; 19:6) those gifts ceased to exist two thousand years ago. In a nutshell, those gifts were given to prove to unbelievers that the Gospel message was authentic. Jesus told some Pharisees that a person can claim anything they say to be divine. To back up His claim for who He was, he did miraculous healings. (Mark 2:2-13)
For those who say, “Well, who are you to say God is not speaking to them? You don't know.” Note the book of Jeremiah:
“Behold, I am against the prophets,” declares the LORD, “who use their tongues and declare, 'declares the LORD.' Behold, I am against those who prophesy lying dreams,” declares the LORD, “and who tell them and lead my people astray by their lies and their recklessness, when I did not send them or charge them. So they do not profit this people at all,” declares the LORD. (Jer 23:31-32)
“Do not let your preachers deceive you, and do not listen to their dreams, for it is a lie that they are preaching to you in my name; I did not send them,” declares the LORD. (Jer 29:8-9) (paraphrased)
