Warfield on Phil 2:5-11:
We need to note carefully . . . that it is not self-depreciation, but self-abnegation, that is thus commended to us. If we would follow Christ, we must, every one of us, not in pride but in humility, yet not in lowness but in lowliness, not degrade ourselves but forget ourselves, and seek every man not his own things but those of others. . . .--B. B. Warfield, 'Imitating the Incarnation,' pp. 6, 8
We cannot be self-consciously self-forgetful, selfishly unselfish. Only, when we humbly walk this path, seeking truly in it not our own things but those of others, we shall find the promise true, that he who loses his life shall find it. Only, when, like Christ, and in loving obedience to His call and example, we take no account of ourselves, but freely give ourselves to others, we shall find, each in his measure, the saying true of himself also: 'Wherefore also God hath highly exalted him.'
The path of self-sacrifice is the path to glory.
Isn't this, in essence, exactly what Paul was commending Timothy and Epaphroditus for in the latter half of Philippians 2?
God get us there.
