One of the great truths in Scripture. “But ye have an unction from the Holy One, and ye know all things” (1 John 2:20). As believers, we are indwelt with the Holy Spirit. We have understanding. Perception. Discernment. We can distinguish truth from lies. Man’s opinion from God’s word. Learn how to think. Reexamine what you believe and why. Is it sound doctrine?
So go ahead. Go to the Holy Scriptures. Read. Study. And wait for God to open your eyes of understanding. What a gift!
