Charles Ellicott Commentary Hebrews 11:40

"God having provided some better thing concerning us, that apart from us they should not be made perfect." — Hebrews 11:40 (ASV)

For us.—Rather, concerning us, that without (or, apart from) us they should not be made perfect. Some better thing—better than they had received (Matthew 13:17; 1 Peter 1:10–11).

The design of God was that they and we may be perfected together; first in the joint reception of mature knowledge and privilege through the High-priestly work of the Lord Jesus (1 Peter 1:12); and then that we with them may, when the end shall come, “have our perfect consummation and bliss both in body and soul, in the eternal and everlasting glory of God.”
