Ephesians 4:30

Grieve. Gr. lupedo, “to cause pain,” “to distress,” “to grieve.” The Greek phrase may be translated, “stop grieving.” The personality of the Holy Spirit is here clearly implied; only persons can be grieved. For the manner in which the Holy Spirit may be grieved see on Matt. 12:31.

Sealed. As in ch. 1:12, 13 believers were said to be sealed “in Christ,” so here they are said to be sealed in the “holy Spirit” (see on Eph. 1:13; cf. 2 Cor. 1:22). For the significance of the seal see on Rev. 7:2. The reception of the Holy Spirit at conversion is God’s authentication that the believer is accepted, that the approval of Heaven rests upon his choice and experience.

Unto. Rather, “with a view to.” It is hoped that the believer will persevere and that he will be glorified. This can be only if he holds “fast the confidence and the rejoicing of the hope firm unto the end” (Heb. 3:6). The act of sealing does not forever guarantee salvation, for it is possible to sin against the Holy Spirit and thus forfeit redemption (see on Matt. 12:31; cf. on Heb. 6:4-6). The sin for which there is no pardon comes as a climax to a series of grievings. It is important therefore to guard against even a single act of grieving.

Redemption. See on ch. 1:14.
