We all have characters: Christ had none: every single faculty in Him was a perfect model, demonstrating God in everything. We may find a display of character in Paul. He repented of having written an inspired epistle. God took care to use him, but he had the sympathies and failings of a fallen man. Hence the need of a "thorn in the flesh"
Perhaps the highest character of spiritual guidance, is not such as " do not go into Bithynia," but by communion with the intelligence of God (see Phil. 1:9; Col. 1:9). Much of the guidance of the Divine life is like this:-If a person has been much in communion with God in prayer, previously, he would often be able to decide upon a matter instantly, by a sort of spiritual intelligence; whereas, if this had not been the case, he might be greatly at a loss, and have to pray much about it before he got light upon his path.
A person walking with God, and self dead, would be positively guided-but motives often bias us unconsciously.
