A.T. Robertson Commentary Luke 15:24

"for this my son was dead, and is alive again; he was lost, and is found. And they began to be merry." — Luke 15:24 (ASV)

And is alive (κα ανεζησεν). First aorist active indicative of αναζαω, to live again. Literally, he was dead and he came back to life.

He was lost (ην απολωλως, periphrastic past perfect active of απολλυμ and intransitive, in a lost state) and he was found (ευρεθη). He was found, we have to say, but this aorist passive is really timeless, he is found after long waiting (effective aorist) The artists have vied with each other in picturing various items connected with this wonderful parable.
