Surely the arm of the Lord is not too short to save

Isaiah 59:1-21
Surely the arm of the Lord is not too short to save, nor his ear too dull to hear. But your iniquities have separated you from your God, so that he will not hear.
Sins: hands are stained with blood, fingers with guilt, lips have spoken lies, tongue mutters wicked things.
"The Redeemer will come to Zion, to those in Jacob who repent of their sins," declares the Lord.
As for me, this is my covenant with them, says the Lord. "My Spirit, who is on you, and my words that I have put in your mouth will not depart from your mouth, or from the mouths of your children, or from the mouths of their descendants from this time on and forever," says the Lord.
For the love of the Lord, his arm worked salvation for them and his own righteousness sustained them.
The prophet points the people to the heart of the matter - the problem is their sin which cuts them off from God.
Why?
It is not the Lord doesn't listen your prayer, but because of our sins separated from God. Repent to the Lord and confess our sin, through Jesus blood and erase out guilt.
Check out behaviors: most of us have not the blood, but may be our decision may cause other's blood bleeding. Care our lips say the truth only.
The arm of the Lord is not short, trust and believe in Him. He is my savior, my redeemer.
Two ways are opening up in these chapters: a safe path that leads to blessing for those who respond to God: a dangerous road leading to destruction for those who choose not to.
What God, in his amazing love.
How?
Amazing grace of the Lord! How great you are, O Lord. You have covenant to me and you have complete salvation on me. Praise the Lord.
