Ephesians 2 refutes the intercession argument: the elect were still under wrath after the cross, before believing

Ephesians 2:1-3: the Ephesian believers were once dead in trespasses, children of wrath. If Christ's intercession from the cross automatically secures salvation for those he died for, the elect should have been saved from the moment of the cross. But Ephesians 2 shows they were still under wrath until they believed. This breaks the Calvinist construct that intercession automatically and immediately applies salvation.
