All that we have spoken of in this site is based upon the foundation of Christ’s sufficiency.
Our salvation depends entirely upon His completed and totally-sufficient work on the cross.
Which is what distinguishes the true gospel from the countless counterfeit gospels that exist in the world. Making faith in Christ alone, by faith alone, by grace alone the separating distinctives from all else that falsely calls itself, “Christian”.
But that is only the beginning of the matter.
