(3) Therefore [we are] always (d) confident, knowing that, whilst we are at home in the body, we are absent from the Lord:
(3) He concludes something here from verse four, and states it in the following way: "Therefore, seeing that we know by the Spirit that we are strangers so long as we are here, we patiently suffer this delay (for we are now so with God, that we behold him only by faith, and are therefore now absent from him) but so that we aspire and have a longing always to him. Therefore also we behave ourselves in such a way that we may be acceptable to him, both while we live here, and when we go from here to him." (2 Corinthians 5:4)
(d) He calls them "confident" who are always resolved with a quiet and settled mind to suffer any danger at all, not doubting at all that their end will be happy.
