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. 1:99And this I pray, that your love may abound yet more and more in knowledge and in all judgment; (Philippians 1:9); Col. 1:99For this cause we also, since the day we heard it, do not cease to pray for you, and to desire that ye might be filled with the knowledge of his will in all wisdom and spiritual understanding; (Colossians 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.
