Matthew 24:36-44 Revised Standard Version (RSV)
The Necessity for Watchfulness
36 “But of that day and hour no one knows, not even the angels of heaven, nor the Son,[a] but the Father only. 37 As were the days of Noah, so will be the coming of the Son of man. 38 For as in those days before the flood they were eating and drinking, marrying and giving in marriage, until the day when Noah entered the ark, 39 and they did not know until the flood came and swept them all away, so will be the coming of the Son of man. 40 Then two men will be in the field; one is taken and one is left. 41 Two women will be grinding at the mill; one is taken and one is left. 42 Watch therefore, for you do not know on what day your Lord is coming. 43 But know this, that if the householder had known in what part of the night the thief was coming, he would have watched and would not have let his house be broken into. 44 Therefore you also must be ready; for the Son of man is coming at an hour you do not expect.
Romans 13:11-14 Revised Standard Version (RSV)
An Urgent Appeal
11 Besides this you know what hour it is, how it is full time now for you to wake from sleep. For salvation is nearer to us now than when we first believed; 12 the night is far gone, the day is at hand. Let us then cast off the works of darkness and put on the armor of light; 13 let us conduct ourselves becomingly as in the day, not in reveling and drunkenness, not in debauchery and licentiousness, not in quarreling and jealousy. 14 But put on the Lord Jesus Christ, and make no provision for the flesh, to gratify its desires.
