William Burkitt on John 3:19

Observe here, 1. The worth and dignity of a choice and invaluable privilege declared, Light is come into the world. A personal light, CHRIST; a doctrinal light, the Gospel.

Observe, 2. The unworthiness, abuse, and great indignity which the world, through infidelity, offers to this benefit: they reject it, and love darkness rather than light.

Observe, 3. The dreadful sentence of wrath which the rejection of this benefit, and the abuse of Christ, brings upon the impenitent and unbelieving world. It terminates in their full and final condemnation: This is the condemnation; that is, 'tis a just and righteous condemnation, 'tis an inevitable and unavoidable condemnation: 'tis an heightened and aggravated, 'tis an accelerated and hastened, an irrecoverable and eternal condemnation.

Learn hence, That the greater and clearer the light is, under which the unregenrated and impentient do live in this world, so much the heavier will their condemnation and misery be in the world to come, if they wilfully and finally reject it.
