In Romans 4: 16 Paul reiterates that “Therefore, the promise comes by faith". This is the key – Faith. The word is repeated in Chapters 4 and 5 many times. Abraham could not “justify” his good standing with God by his good works; it was credited to him by his strong Faith. In the context of Chapter 5 Dr Wilson has defined Justification to mean vindication, as if being released from guilt, pardoned. This release is only gained through Faith in Jesus Christ. My definition of justification, in my understanding, means that I stand innocent, no longer accused. I should stand secure in this knowledge.
