All God's revelations are sealed to us until they are opened to us by obedience. You will never get them open by philosophy or thinking. Immediately you obey, a flash of light comes. Let God's truth work in you by soaking in it, not by worrying into it. Obey God in the thing He is at present showing you, and instantly the next thing is opened up. We read tomes on the work of the Holy Spirit when... five minutes of drastic obedience would make things clear as a sunbeam. We say, "I suppose I shall understand these things some day." You can understand them now: it is not study that does it, but obedience. The tiniest fragment of obedience, and heaven opens up and the profoundest truths of God are yours straight away. God will never reveal more truth about Himself till you obey what you know already. Beware of being wise and prudent.
