Christ not only makes us alive to the love of God in this life but takes right through physical death into the fulness of God's love in heaven. A key passage is Paul's explanation in the Epistle to the Romans. If the many died through the one man's trespass, much more surely have the grace of God and the free gift in the grace of the one man, Jesus Christ, abounded for the many. And the free gift is not like the effect of the one man's sin. Those who prefer a model of Original Sin tend to give a Roman lawcourt meaning to these words.
Condemnation is the sentence to eternal damnation.
Justification is being counted righteous because Christ paid the penalty of due to our sin when he died on the cross. In a model of Creative Love Theism condemnation is the sense of guilt and shame that makes us hide, as Adam and Eve did, from the Son of God instead of walking joyfully with him. There are then two ways of living one's life in the world either in Christ or hiding from him. This is a translation of the Greek word dikaioma from the verb dikaioo which can have the sense of a law court vindication. We cannot tell from the Greek words alone what they mean.
