J. N. Darby

The Lord's coming again into this world assumes therefore a very different character from that of a vague object of hope to a believer as a period of glory. In 1 Thessalonians 5 the apostle speaks of it, but in order to distinguish between the position of Christians and that of the careless and unbelieving inhabitants of the earth. The Christian, alive and taught of the Lord, ever expects the Master. There are times and seasons; it is not needful to speak to him concerning them. But (and he knows it) the day of the Lord will come, and like a thief in the night, but not for him: he is of the day; he has part in the glory which will appear in order to execute judgment on the unbelieving world. Believers are the children of light; and this light, which is the judgment of unbelievers, is the expression of the glory of God — a glory which cannot endure evil, and which, when it shall appear, will banish it from the earth. The Christian is of the day that will judge and destroy the wicked and wickedness itself from off the face of the earth. Christ is the Sun of righteousness, and the faithful will shine as the sun in the kingdom of their Father.
