Only God can wash our sin, through Jesus Christ

Isaiah 1:10-20
Stop bringing meaningless offerings! Your incense is testable to me. I cannot bear your evil assemblies.
The Lord hide his eyes when they pray, for their hands are full of blood.
How to let the Lord delight? 1)wash and make clean, take evil deeds out, stop doing wrong! 2) Learn to do right! Seek justice, encourage the oppressed. Defend the cause of the fatherless, plead the case of the widow.
If you are willing and obedient, you will eat the best from the land; but if you resist and rebel, you will be devoured by the sword.
Scarlet, red as crimson: Both are color-fast; only God could 'wash' these out.
Why?
God is sickened by their moral degradation, social injustice and religious hypocrisy. The language is extreme.
God's people are his 'enemies'. Yet God offers forgiveness.
Wash the sins: Stop doing wrong right now!
Learn to do right: Most people don't know how to do right, so the Lord guides them from four direction to do the right things.
We attend the worship in church and have offering to the Lord, but does my behavior and my heart is plead to the Lord almighty?
How?
Repent and do the right, then the Lord washes our sin from red to white as snow.
Through Jesus Christ only our sins could be washed!
