Was my arm too short to deliver you? Do I lack the strength to rescue you?

Isaiah 50:1-11
Because of your sins you were sold; because of your transgressions your mother was sent away.
When I came, why was there no one? When I called, why was there no one to answer? Was my arm too short to deliver you? Do I lack the strength to rescue you? By a mere rebuke I dry up the sea, I turn rivers into a desert; their fish rot for lack of water and die of thirst.
Because the Sovereign Lord helps me, I will not be disgraced. Therefore have I set my face like flint, and I know I will not be put to shame.
Who among you fears the Lord and obeys the word of his servant? Let the one who walks in the dark, who has no light, trust in the name of the Lord  and rely on their God. But now, all you who light fires and provide yourselves with flaming torches, go, walk in the light of your fires and of the torches you have set ablaze. This is what you shall receive from my hand: You will lie down in torment.
In the third Servant Song, for the first time we glimpse his suffering and rejection. But nothing can deflect him from his purpose.
Why?
Was my arm too short to deliver you? Do I lack the strength to rescue you?  God can save us God is the sovereign Lord, but for our sins and transgressions so we were suffered and be sent away.
Isaiah gave us the way that the Sovereign Lord helps me, I will not be disgraced.
Who among you fears the Lord and obeys the word of his servant?  This is the key to be blessed.
There is dark and not light, people though it is the day light or torch, but God is the light of our soul and heart. God's light can show our inner sins and transgression in our mind. But very sad that most people still hard their neck and heart, walk on their won way. They thought that is right way, but to the downfall.
How?
Fear the Lord and obey the word of his servant.
