“God having provided some better thing for us, that they without us should not be made perfect.”
King James Version (KJV)
11:40 God having provided some better thing for us - Namely, everlasting glory. That they might not be perfected without us - That is, that we might all be perfected together in heaven.
Heb 11:40 God having provided some better thing for us. The new and better covenant, the gospel, the realization of the promises made to Abraham. That they without us should not be made perfect. That they and we together might be made complete in the city whose builder and maker is God. The full fruition, the being made complete (perfect) belongs to the heavenly state. All these ancient heroes, who died not having received the promise, need the realization of the promise in Christ to make them perfect; by that promise we also are saved.
