15:13 See “Hope” at Heb. 6:18. What was described as the effect of Scripture in v. 4 (having hope) is now attributed to the work of the Holy Spirit. Paul here follows a pattern evident throughout the New Testament in which God’s saving acts are attributed to God’s Word as well as to the work of the Holy Spirit (e.g., regeneration, 1 Pet. 1:23; sanctification, John 17:17; salvation, Rom. 1:16; searching the heart, Heb. 4:12).
