Warfield on Christian self-sacrifice

From a sermon on Philippians 2:5-8:

It is not to mere self-denial that Christ calls us, but specifically to self-sacrifice: not to unselfing ourselves, but to unselfishing ourselves. Self-denial for its own sake is in its very nature ascetic, monkish. It concentrates our whole attention on self—self-knowledge, self-control—and can therefore eventuate in nothing other than the very apotheosis of selfishness. . . . It is not to this that Christ's example calls us. He did not cultivate self, even His divine self: He took no account of self. He was not led by His divine impulse out of the world, driven back into the recesses of His own soul to brood morbidly over His own needs, until to gain His own seemed worth all sacrifice to Him. He was led by His love for others into the world, to forget Himself in the needs of others, to sacrifice self once for all upon the altar of sympathy. Self-sacrifice brought Christ into the world. And self-sacrifice will lead us, His followers, not away from but into the midst of men. Wherever men suffer, there will we be to comfort. Wherever men strive, there will we be to help. Wherever men fail, there will be we to uplift. Wherever men succeed, there will we be to rejoice. Self-sacrifice means not indifference to our times and our fellows: it means absorption in them. It means forgetfulness of self in others. It means entering into every man's hopes and fears, longings and despairs: it means manysidedness of spirit, multiform activity, multiplicity of sympathies. It means richness of development. It means not that we should live one life, but a thousand lives—binding ourselves to a thousand souls by the filaments of so loving a sympathy that their lives become ours. It means that all the experiences of men shall smite our souls and shall beat and batter these stubborn hearts of ours into fitness for their heavenly home. It is, after all, then, the path to the highest possible development, by which alone we can be made truly men.
