Imminence

The Day is at Hand- This must therefore be imminent:
(at hand means imminent Matt.26:45-7 Then cometh he to his disciples, and saith unto them, Sleep on now, and take your rest: behold, the hour is at hand, and the Son of man is betrayed into the hands of sinners. Rise, let us be going: behold, he is at hand that doth betray me. And while he yet spake, lo, Judas, one of the twelve, came, and with him a great multitude with swords and staves, from the chief priests and elders of the people. Mark 14:42-3 Rise up, let us go; lo, he that betrayeth me is at hand. And immediately, while he yet spake, cometh Judas...)

Romans 13:11-12 And that, knowing the time, that now it is high time to awake out of sleep: for now is our salvation nearer than when we believed. The night is far spent, the day is at hand: let us therefore cast off the works of darkness, and let us put on the armour of light.
James 5:8-9 Be ye also patient; stablish your hearts: for the coming of the Lord draweth nigh. Grudge not one against another, brethren, lest ye be condemned: behold, the judge standeth before the door. (Note that ‘before the door’ is a phrase indicating imminence as here in Mt.24:33- So likewise ye, when ye shall see all these things, know that it is near, even at the doors. Also see Mk.13:29.)
1 Pet.4:7 But the end of all things is at hand: be ye therefore sober, and watch unto prayer.

Behold, I come quickly, suddenly, shortly. (Mk.13:36, Rev.1:1,3,2:5,16,3:3,11,16:15,22:6,7,10,12,20)

Mark 13:32-37 But of that day and that hour knoweth no man, no, not the angels which are in heaven, neither the Son, but the Father. Take ye heed, watch and pray: for ye know not when the time is. For the Son of Man is as a man taking a far journey, who left his house, and gave authority to his servants, and to every man his work, and commanded the porter to watch. Watch ye therefore: for ye know not when the master of the house cometh, at even, or at midnight, or at the cockcrowing, or in the morning: Lest coming suddenly he find you sleeping. And what I say unto you I say unto all, Watch.
Luke 12:37 Blessed are those servants, whom the lord when he cometh shall find watching: verily I say unto you, that he shall gird himself, and make them to sit down to meat, and will come forth and serve them. v40-41 Be ye therefore ready also: for the Son of man cometh at an hour when ye think not. Then Peter said unto him, Lord, speakest thou this parable unto us, or even to all?
v46 The lord of that servant will come in a day when he looketh not for him, and at an hour when he is not aware, and will cut him in sunder, and will appoint him his portion with the unbelievers.
The admonition to watch is to watch for Christ himself to appear. (Mt.24:42-3, 50, 25:13, Mk.13:33-7, Lk.12:37-48, 21:36, Phil.3:20, 1 Thes.5:6, Tit.2:13, 1 Pt.4:7, 2 Pt.3:12, 1 Jn.2:28, Rv.3:3, 16:15)
