And St. Paul's language does not let us suppose that the whole of what he means by our 'salvation' is included in our preliminary acceptance[[3]]. That is simply our first introduction into a permanent state. Our 'salvation' is here, as elsewhere, spoken of as equivalent to deliverance from wrath in the day of judgement, which means that our whole moral being has become such as can bear the scrutiny of the divine righteousness and the fellowship of the divine glory.
2. Where the Revised Version above[[4]] reads 'rejoice,' it is important to remember that the word is that used for the illegitimate 'glorying' or 'boasting' of iii. 27 and iv. 2. Christians have something to boast of, but it is not their own; it is God's gift. Therefore they are especially delighted when God's strength is shown in their weakness, and they will more particularly 'boast of their weaknesses' (cf. 2 Cor. xi. 30).
3. St. Paul's argument that the Christian hope is fundamentally trustworthy is based, we may notice, on a twofold appeal. First (ver. 5), he appeals to the gift of the Spirit which at a definite time[[5]] each Christian received, doubtless by the laying on of hands. This gift is in itself an outpouring of the divine love and an 'earnest' of future glory (2 Cor. i. 22, v. 5). No doubt almost all the Christians had more or less intensely felt the reality of the divine love in the indwelling Spirit. But St. Paul lays stress rather on the fact than on the feeling. Secondly (vers. 6 ff.), he appeals to the great redemptive act of God. God had gone out of His way to make a great sacrifice in order to reconcile us when we were enemies, and therefore may be trusted to carry out the preliminary reconciliation into full spiritual deliverance or salvation by Christ's life. The greater effort carries with it the less.
