Through Jesus Christ we are children of light.
For yourselves know perfectly that the day of the Lord so cometh as a thief in the night. 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. 1 Thessalonians 5:2, 4-6 KJV https://bible.com/bible/1/1th.5.2-6.KJV
