I Count All Things But Loss

"I count all things but loss for the excellency of the knowledge of Christ Jesus my Lord." (Philippians 3:8)

Yea, doubtless, and I count all things [but] loss

Anything and everything that stood in competition with Christ.  All the worldy substance, the comfort of life and life itself.

 for the excellency of the knowledge of Christ Jesus my Lord:

 That knowledge which believers have of him, who know him not only in his person, as God over all, but as a Saviour and Redeemer, and as theirs; they know him in all his relations, and particularly as their Lord, not by creation only, but by redemption and grace, as the apostle did, putting an emphasis on these words, "my Lord"; thereby expressing his faith of interest in him, his great affection for him, and cheerful subjection to him.

It is attained to, not by the light of nature, nor by the help of carnal reason, nor by the law of Moses, but by the Gospel of the grace of God, as a means; and the efficient cause of it is Father, Son, and Spirit; the Father reveals Christ in his saints; the Son gives them an understanding to know him; and the Spirit is a spirit of wisdom and revelation in the knowledge of him; and this knowledge is very excellent: a spiritual knowledge of Christ

It is not in the book of nature, nor in the schools of the philosophers; it is not of earth, nor earthly, but it comes from afar, from above, from heaven, from God the Father of lights; it is a free grace gift, a distinguishing one, and is very comprehensive, unspeakable, and unchangeable: and as to the object of it, it is Christ, the chiefest among ten thousands; who made the heavens, earth, and seas, and all that in them are, the sun, moon, and stars, men and beasts, birds and fishes, fossils, minerals, vegetables, and everything in nature; and therefore the knowledge of him must be superior to the knowledge of everything else.

for whom I have suffered the loss of all things;
he dropped all confidence in his carnal privileges, and civil, ceremonial, and moral righteousness, for Christ and his righteousness; he parted with all for this pearl of great price; he lost his good name, credit, and reputation among men, and suffered afflictions and persecutions in various shapes; he lost the comforts of life, being often in cold and nakedness, in hunger and thirst, and was ready to suffer the loss of life itself for professing and preaching Christ: and do count them [but] dung;
or dog's meat;  what is fit only to be cast to dogs, as the word signifies; and intends every thing that is base, mean, and worthless; as the faeces of men, the dregs and lees of liquor, the falling of fruit, chaff, stubble, the dross of metals, dung, and what not: so he esteemed his carnal descent; his form and sect of religion, and zeal in it; his ceremonial and moral righteousness before and after conversion; and everything of the creature, or what was his own, and but flesh; being of the same opinion with the church of old, who reckoned her righteousnesses, the best, and the whole of them, as "filthy rags". The apostle next expresses his end and views in this, that I may win Christ;
 The apostle's meaning is, either that he might gain or acquire a larger knowledge of Christ; and he cared not what pains he took, what expenses he was at, nor what loss he sustained for what he esteemed the most excellent, and for which he had already suffered the loss of all things; and if he had had more to lose, he could willingly part with it for more of this knowledge; or his sense is, that he might gain by Christ, or that Christ might be gain to him, as he found him to be, and as he is to every believer; who by parting with all for Christ, gains much by him, as a justifying righteousness, acceptance with God, peace, pardon, life, grace, and glory.
