Here's a friendly reminder from Jonathan Edwards who explains that you will never know enough doctrine, nor even explore all there is to know of God. So, my fellow theology nerds pay attention:
However diligent we apply ourselves, there is room enough to increase our knowledge in divine truth. None have this excuse to make for not diligently applying themselves to gain knowledge in divinity, that they already know all; nor can they make this excuse, that they have no need diligently to apply themselves, in order to know all that is to be known. None can excuse themselves for want of business in which to employ themselves. There is room enough to employ ourselves for ever in this divine science, with the utmost application. Those who have applied themselves most closely, have studied the longest, and have made the greatest attainments in this knowledge, know but little of what is to be known. The subject is inexhaustible. That divine Being, who is the main subject of this science, is infinite, and there is no end to the glory of his perfections. His works at the same time are wonderful, and cannot be found out to perfection; especially the work of redemption, about which the science of divinity is chiefly conversant, is full of unsearchable wonders.
The word of God, which is given for our instruction in divinity, contains enough in it to employ us to the end of our lives, and then we shall leave enough uninvestigated to employ the heads of the ablest divines to the end of the world. The psalmist found an end to the things that are human; but he could never find an end to what is contained in the word of God: Psal. cxix. 96. "I have seen an end to all perfection; but thy command is exceeding broad." There is enough in this divine science to employ the understandings of saints and angels to all eternity.
