To all who are willing for self to be humbled are given God's promises:
 

"I will make all My goodness pass before thee, and will proclaim the name of Jehovah before thee." Exodus 33:19, A. R. V.
 

"Call unto Me, and I will answer thee, and show thee great and mighty things, which thou knowest not." Jeremiah 33:3.
 

"Exceeding abundantly above all that we ask or think," will be given unto us, "the Spirit of wisdom and revelation in the knowledge of Him," that we "may be able to comprehend with all saints what is the breadth, and length, and depth, and height; and to know the love of Christ, which passeth knowledge," that we may be "filled with all the fullness of God." Ephesians 3:20; 1:17; 3:18, 19.
 

This is the knowledge which God is inviting us to receive, and beside which all else is vanity and nothingness.
