KJV:
For all that is in the world, the lust of the flesh, and the lust of the eyes, and the pride of life, is not of the Father, but is of the world.
NKJV:
For all that is in the world—the lust of the flesh, the lust of the eyes, and the pride of life—is not of the Father but is of the world.
NIV:
For everything in the world—the lust of the flesh, the lust of the eyes, and the pride of life—comes not from the Father but from the world.
Interpretation:
The pride of life comes from the world, not from the Father. The verse identifies pride as one of the main temptations of the world. Pride of life means boasting about what we have or what we've achieved. It comes from valuing worldly things above spiritual things. The verse teaches that pride is fundamentally worldly. It doesn't come from God but from the fallen world system. Believers must resist the pride of life because it separates us from the Father.
