The achievement of the gospel

Mark 11:27-12:12
Jesus was questioned where his authority come from? Jesus replied with another question as deal to answer them. Because they won't believe in Him.
Jesus said a parable about the tenants, tenants rent the vineyard from the Lord, Jesus is the son of the host. The vineyard is belong to the host, but the tenants don't care the master, even kill his son, try to take over his inheritance.
The stone the builders rejected has become the capstone, the Lord has done this, and it is marvelous in our eyes. (Psalm 118:22,23)
Why?
Jesus, the carpenter from the north, with no formal training in the Jewish law, strolls among the shaded colonnades of the Temple, teaching his followers in the manner of the best-qualified rabbi. No wonder the religious 'professionals' question his authority.
His reply, and the condemnatory parable that follows, silences them. They withdraw to take stock and renew their attack.
Reply question depends on who asked, if he does not trust or has against us. Do not have to reply directly, but with wisdom to reject them. Jesus has wisdom above all.
How?
Dear Lord please let me have those wisdom to preach gospel,not only with my strength bur also with the wisdom from you.
God is waiting for me return the achievement of the gospel He has given me
