{If thou wouldest be perfect} (ei theleis teleios einai).
Condition of the first class, determined as fulfilled. Jesus
assumes that the young man really desires to be perfect (a big
adjective that, perfect as God is the goal,  5:48 ). {That thou
hast} (sou ta huparchonta). "Thy belongings." The Greek neuter
plural participle used like our English word "belongings." It was
a huge demand, for he was rich.
