What I felt He is showing me here, is that He is at the right hand of Father UNTIL, the time comes to make His enemies His footstool, then He no longer stays there, but comes down to earth to make war. [ See Isaiah 42 ]

2    The Lord will send forth from Zion the scepter of Your strength; rule, then, in the midst of Your foes. [Rom 11:26,27.]

Isa 18:4 NKJV  For so the LORD said to me, "I will take My rest, And I will look from My dwelling place Like clear heat in sunshine, Like a cloud of dew in the heat of harvest."

Isa 26:17-19 NKJV   As a woman with child Is in pain and cries out in her pangs, When she draws near the time of her delivery, So have we been in Your sight, O LORD. 18  We have been with child, we have been in pain; We have, as it were, brought forth wind; We have not accomplished any deliverance in the earth, Nor have the inhabitants of the world fallen. 19 Your dead shall live; Together with my dead body* they shall arise. Awake and sing, you who dwell in dust; For your dew is like the dew of herbs, And the earth shall cast out the dead. 

Hos 14:5 NKJV  I will be like the dew to Israel; He shall grow like the lily,
And lengthen his roots like Lebanon.

Zech 8:11-13  NKJV  But now I will not treat the remnant of this people as in the former days,' says the LORD of hosts. 12 'For the seed shall be prosperous, The vine shall give its fruit, The ground shall give her increase,And the heavens shall give their dew — I will cause the remnant of this people To possess all these. 13 And it shall come to pass that just as you were a curse among the nations, O house of Judah and house of Israel, so I will save you, and you shall be a blessing. Do not fear, Let your hands be strong.'

4   The Lord has sworn and will not revoke or change it: You are a priest forever, after the manner and order of Melchizedek. [Heb 5:10; 7:11,15,21.]

Jesus is our FOREVER HIGH PRIEST ever interceding for the saints until they
Are perfected.  And this is a covenant – it cannot be broken.

5   The Lord at Your right hand will shatter kings in the day of His indignation.  6   He will execute judgment [in overwhelming punishment] upon the nations; He will fill the valleys with the dead bodies, He will crush the [chief] heads over lands many and far extended. [Ezek 38:21,22; 39:11,12.]

7          He will drink of the brook by the way; therefore will He lift up His head [triumphantly].

The Lord will fight at our RIGHT HAND.  See Isaiah 58, Ps 121 says;

Ps 121:5-8 NKJV The LORD is your keeper; The LORD is your shade at your
           right hand. 6 The sun shall not strike you by day, Nor the moon by
