This is great teaching from Oswald Chambers on how we come to know God and spiritual truth. I encourage you to take it to heart and act upon it. It will revolutionize your spiritual life.
All God’s revelations are sealed 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. The only way you can get to know is to stop trying to find out and by being born again. Obey God in the thing He shows you, and instantly the next thing is opened up. We read tomes on the work of the Holy Spirit, when one five minutes of drastic obedience would make things as clear as a sunbeam. ‘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 and the profoundest truths of God are yours straight away. God will never reveal more truth about Himself until you have obeyed what you know already. Beware of becoming “wise and prudent.”
