27:18 There are in the world today many who close their eyes to the evidences that Christ has given to warn men of His coming. They seek to quiet all apprehension, while at the same time the signs of the end are rapidly fulfilling, and the world is hastening to the time when the Son of man shall be revealed in the clouds of heaven. Paul teaches that it is sinful to be indifferent to the signs which are to precede the second coming of Christ. Those guilty of this neglect he calls children of the night and of darkness. He encourages the vigilant and watchful with these words: "But ye, brethren, are not in darkness, that that day should overtake you as a thief. Ye are all the children of light, and the children of the day: we are not of the night, nor of darkness. Therefore let us not sleep, as do others; but let us watch and be sober."
