Who will separate us from the love of Christ? Will hardship, or distress, or persecution, or famine, or nakedness, or peril, or sword? As it is written,
“For your sake we are being killed all day long;
we are accounted as sheep to be slaughtered.”
No, in all these things we are more than conquerors through him who loved us. For I am convinced that neither death, nor life, nor angels, nor rulers, nor things present, nor things to come, nor powers, nor height, nor depth, nor anything else in all creation, will be able to separate us from the love of God in Christ Jesus our Lord. (Romans 8:34-39)
The time between Christ’s Ascension into heaven and His second coming to earth is the time of the Church. The Church really is that interstice between the two comings of Christ – participating in both this world and that world which is to come. So while Christians are called to rejoice always and to give thanks in all circumstances (1 Thessalonians 5:16-18), we find ourselves in a world in which there still is great sorrow and suffering and we still must wait for that world in which sickness, sorrow and suffering have passed away (Revelation 21:4). Biblical scholar Richard B. Hays comments on how St. Paul deals with the current age, the time of the Church awaiting Christ’s return:
“Paul reads the Psalm  as a prophetic prefiguration of the experience of the Christian church, so that the text finds its true primary meaning in Paul’s own present time. The point is not that ‘righteous people have always suffered like this’ rather, Paul’s point in Rom. 8:35-36 is that Scripture prophesies suffering as the lot of those (i.e., himself and his readers) who live in the eschatological interval between Christ’s resurrection and the ultimate redemption of the world. Thus, in this instance . . . Paul discerns in Scripture a foreshadowing of the church.
This psalm raises plaintively the issue that we have already seen to be the central theological problem of Romans: the question of God’s integrity in upholding his promises to Israel. Paul is struggling to vindicate God from the suspicion of capriciousness in choosing to ‘justify’ Gentiles who do not observe the Torah. Is God a fickle god who has cast off Israel (cf. Rom 3:1-8, 3:21-26, 3:31, 9:14, and all of chapters 9-11)?
The psalmist raises a question precisely analogous to the one that Paul is seeking to answer: does the community’s experience of suffering indicated that God has abandoned them?
But there is still one more significant overtone to be heard in Paul’s quotation of Psalm 44. The psalmist’s main point in verses 17-22 is that the suffering of Israel cannot be construed as a punishment for unfaithfulness or idolatry; on the contrary, God’s people suffer precisely because of their faithfulness to him.” (Echoes of Scripture in the Letters of Paul, 58-60)
