"Lean not to thine own understanding..."
Having a pretty good memory, early on in my walk with God I had quickly acquired the ability to quote a lot of Scripture. People would ask me questions. They started seeking my counsel. But I withdrew from the influence that seemed to come from Bible knowledge because I realized I didn't have practical experience of what the text seemed to speak about. I didn't know how to be delivered from bondage to corruption. I had to eventually come through some very terrible dealings with God.
The crisis that is particularly relevant here has to do with what I understood as believing the Bible. For several years I had tried constantly to find work. I prayed and fasted. I earnestly strove with God, reminding Him that He was the one who'd made me care to walk uprightly as a man of integrity. It was His word that said to, "Work with your own hand and arm to provide for yourself and to give to others." Nothing worked. My mind had gone over the problem repeatedly. God said if we weren't willing to work neither should we eat. I was willing and it was God's will according to the Bible. How come wasn't God giving me work? My experience didn't match what I found in Scripture. I couldn't believe any different. To obsessively examine the pieces of the puzzle that you have does not result in more pieces. I couldn't think anymore. I fasted and prayed until I couldn't pray anymore. I could only say the name, "Jesus" occasionally every few minutes. That was what I was reduced to.
I ended up homeless in the snow for about six months. What I learned was that I believed in my knowledge and not Scripture. I can only build so much of His word in my heart, in my consciousness. It actually is what God knows He meant. The real Word of God is in His own mind. I can have only an extremely limited, fragmentary and biased portion of His true word. This is how God broke me from trusting in my own understanding, even my understanding of His word.
I eventually discovered Elijah by the brook being fed by ravens. What work was He doing, unless prayer? (And how dare he request the last food of a dying widow and her child!) But God had hid this in His word from me in order to discipline me. We can have enough relevant word to obey, but stop this arrogant nonsense about believing a Bible you don't even know. He will sever our attachments to our own way and bring about subjection to Him. He doesn't only enlighten us, He forms us. Yes, we've been granted an understanding of the Holy; but, we've also been chastened to walk in His paths.
"He hath shewed thee, O man, what is good; and what doth the LORD require of thee, but to do justly, and to love mercy, and to walk humbly with thy God?" (Micah 6:8)
