I've been wondering this myself. Well said and a short article well worth reading and pondering.
Let me do some critical thinking out loud for a moment. I am pondering two questions. First, if God is speaking to us through visions, dreams, personal prophecies, etc., why is it that so often those who receive these visions, dreams, personal prophecies are some of the weakest people I know? I am not going to lump all charismatics together here as I don't know all of them of course and that would be unfair but those that I do know who claim God is speaking to them in a dream or a "word" in their spirit are typically not committed to studying the Bible, are often ignorant of basic doctrines, don't pray too much, are not serious in evangelism, and for the most part are weak spiritually.
The Bible is the only source of 100% truth, yet people seek experiences rather than real worship as in prayer, Bible study, fellowship, and church attendance in a godly church.
The entirety of Your word is truth, and every one of Your righteous judgments endures forever. (Psalms 119:160, NKJV)
All Scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness, (2 Timothy 3:16, NKJV)
And let us consider one another for the stirring up of love and of good works, not forsaking the assembling of ourselves, just as is the custom for some, but exhorting one another, and all the more as you see the Day drawing near. (Hebrews 10:24-25, EMTV)
Pray without ceasing! (1 Thessalonians 5:17, EMTV)
