Analysis & Commentary

And being fully persuaded that, what he had promised, he was able also to perform. Paul summarizes Abraham's faith: plērophorētheis (πληροφορηθείς, "being fully assured/convinced"). The verb compounds plēros (πλήρος, "full") with phoreō (φορέω, "to carry/bear")—faith that is fully carried through, complete conviction. The content of this assurance has two components:

  1. ho epēggeltai (ὃ ἐπήγγελται, "what He has promised")—God's word stands
  2. dunatos estin kai poiēsai (δυνατός ἐστιν καὶ ποιῆσαι, "He is able also to do")—God's power matches His promise.

    This is the anatomy of justifying faith: full persuasion that God is both truthful (He has promised) and powerful (He is able to perform).

Abraham believed God could do what humanly was impossible—create life from death. This parallels Christian faith: God raised Christ from the dead (v. 24-25), which was equally impossible by natural means. Justifying faith trusts God to do what He has promised (justify the ungodly, v. 5) because He is able (through Christ's atoning death and resurrection). Faith's object, not its intensity, saves.

Historical Context

The connection between promise and power would resonate with Paul's Roman readers familiar with patron-client relationships. A patron's word was only as good as his ability to deliver on it. Paul presents God as the ultimate Patron whose promises are absolutely certain because His power is unlimited. This contrasts with human patrons who might promise much but lack the power or will to follow through.
