A.T. Robertson Commentary 1 Corinthians 15:43

"it is sown in dishonor; it is raised in glory: it is sown in weakness; it is raised in power:" — 1 Corinthians 15:43 (ASV)

In weakness (εν ασθενεια). Lack of strength as shown in the victory of death.

In power (εν δυναμε). Death can never conquer this new body, "conformed to the body of His glory" .
