If your preacher tells you he received a direct revelation from God, he has either deceived himself or he is intentionally deceiving others. That kind of language is how false teachers such as Muhammad and Joseph Smith have deceived billions. It enabled them to please people or manipulate people with the alleged authority of God (1 Kin. 13:18; Jer. 23:16).
Friends, do you know why there is a back cover on your Bible after Revelation 22? God stopped revealing Truth to man in the first century A.D., just as He said He would! (Jn. 16:13). That is why people who have been dead four days are not being raised, why people are not walking on water, etc., because the purpose of miracles was to confirm God’s Word as it was being revealed in the first century A.D. (Mk. 16:20; Heb. 2:3, 4). Now that we have the confirmed and complete Bible as the perfect system of revelation, there is no need for new revelations (and thus no need for miraculous confirmation of revelation), just as God said (1 Cor. 13:8-12).
The Bible is solitarily sufficient for all spiritual instruction, and Paul said anyone who dares to claim they have a different revelation than what God revealed in the first century A.D. is “accursed” (Gal. 1:6-9; cf. Deut. 4:2; Prov. 30:6; Zech. 13:1-3; 2 Tim. 3:16, 17; 4:2-4; Jam. 3:1; 2 Pet. 1:3; Jude 3; 2 Jn. 9-11; Rev. 22:18, 19).
AMEN 🙏🏼. Thank you for a wonderful lesson.
