1 Thessalonians 5
1)But of the times and the SEASONS, brethren, ye have no need that I write unto you. 2)For yourselves know perfectly that the day of the Lord so cometh as a thief in the night. 3)For when they shall say, Peace and safety; then sudden destruction cometh upon them, as travail upon a woman with child; and they shall not escape. 4)But ye, brethren, are not in darkness, that that day should overtake you as a thief. 5)Ye are all the children of light, and the children of the day: we are not of the night, nor of darkness. 6)Therefore let us not sleep, as do others; but let us watch and be sober. 7)For they that sleep sleep in the night; and they that be drunken are drunken in the night. 8)But let us, who are of the day, be sober, putting on the breastplate of faith and love; and for an helmet, the hope of salvation. 9)For God hath not appointed us to wrath, but to obtain salvation by our Lord Jesus Christ.
Genesis 1:14
“And God said, Let there be lights in the firmament of the heaven to divide the day from the night; and let them be for signs, and for SEASONS, and for days, and years:”
We know seasons through the LIGHTS in the FIRMAMENT. Stars, Moon, and Sun. Just look up and you'll know the season. The lights will TELL you.
