II Corinthians 5:20

for Christ . . . in Christ's stead--The Greek of both is the same: translate in both cases "on Christ's behalf." beseech . . . pray--rather, "entreat [plead with you] . . . beseech." Such "beseeching" is uncommon in the case of "ambassadors," who generally stand on their dignity (compare Co2 10:2; Th1 2:6-7). be ye reconciled to God--English Version here inserts "ye," which is not in the original, and which gives the wrong impression, as if it were emphatic thus: God is reconciled to you, be ye reconciled to God. The Greek expresses rather, God was the RECONCILER in Christ . . . let this reconciliation then have its designed effect. Be reconciled to God, that is, let God reconcile you to Himself (Co2 5:18-19).

The apostle proceeds in showing the reasons why they did not faint under their afflictions, namely, their expectation, desire, and assurance of happiness after death (Co2 5:1-5), and deduces an inference for the comfort of believers in their present state (Co2 5:6-8), and another to quicken them in their duty (Co2 5:9-11). Then he makes an apology for seeming to commend himself, and gives a good reason for his zeal and diligence (Co2 5:12-15), and mentions two things that are necessary in order to our living to Christ, regeneration and reconciliation (Co2 5:16 to the end).

5:20 The great privilege of believers is to be Christ’s ambassadors (cp. Eph 6:20). • God is making his appeal through us: Paul doesn’t say that he speaks for God; rather, God speaks his word through us. • Christ’s redeeming work for sinners opens the way for them to “Come back to God!” and be reconciled with him (see Rom 5:1-11; Eph 2:11-22; Col 1:15-23). Christian witness has this appeal at its heart. Paul was also appealing to the rebellious Corinthians to come over to his side (see 2 Cor 6:1).
