15 And Moshiach died, on behalf of all [I Ti 2:6] that the ones living may no longer live to themselves but may live to the one [Moshiach] who both died and has been made to stand up alive in his Techiyas HaMoshiach for their sakes. [Ro 14:7-8]
16 From now on, therefore, we have da'as of no one from a purely human point of view; if indeed we have had da'as of Rebbe, Melech HaMoshiach according to the basar, we now no longer so have da'as of him,
17 So that if anyone is in Moshiach, he is a bria chadasha (a new being) [Ro 8:1,10; Ga 6:15]: the old things passed away; hinei, all has become chadashot. [YESHAYAH 43:18; 65:17; Rv 21:5]
18 And all things are of Hashem, Who is the One having granted to us ritztzuy (reconciliation) to Himself through Moshiach [Ro 5:10] and has given to us the sherut haRitztzuy (the ministry of reconciliation),
19 Davka (specifically), that Hashem was in Moshiach reconciling the Olam to himself, [Ro 3:24-25; Co 1:19-20) Not reckoning their avonot against them and putting in us the Dvar HaRitztzuy (Message of Reconciliation).
20 On behalf of Rebbe, Melech HaMoshiach, therefore, we are emissaries of shalom [YESHAYAH 27:5; 52:7; Ep 6:20], as if Hashem were entreating through us, we ask on behalf of Rebbe, Melech HaMoshiach: be reconciled to Hashem!
21 The one who in his person had no da'as of chattat (sin) [Ac 3:14; Yn 8:46; MJ 4:15; 7:26; 1K 2:22; 1Y 3:5], this one Hashem made a chattat sin offering [Ga 3:13; YESHAYAH 53:10; VAYIKRA 4:24 TARGUM HASHIVIM] on our behalf that we might become the Tzidkat Hashem [DANIEL 9:24] in Moshiach. [1C 1:30; Pp 3:9] [T.N. In this next chapter Rav Sha'ul warns against associations or worldly influences or fascinations that will contaminate the believer, who should not think he can have both the world's evil pleasures and the House of G-d's holy chelek.]
