Colossians 2:3

That is, in Jesus Christ, and in his gospel, are all the treasures of wisdom and knowledge, laid up as in. store-house, and from thence are they only to be expected and derived. The knowledge of Christ and his gospel is an extensive and comprehensive knowledge,. rich and enriching knowledge; the chiefest gain is loss, and the richest treasure is dung, when Christ's riches are displayed; and after all that we have or can attain unto, of the knowledge of Christ, his works is unsearchable, no finite understanding can reach the depth thereof; for in him are hid all the treasures of wisdom and knowledge.
