Salvation: ISA 1:18

Isaiah 1:18
Come now, and let us reason together, saith the Lord: though your sins be as scarlet, they shall be as white as snow.
There is only one solution to the sin question -the problem of your heart being stained with sin - that is the application of the blood of Christ. The only way for your sins to be “as white as snow” is to believe on the Lord Jesus Christ as your Saviour and for Him to wash your sins away. This is salvation. It’s very simple - and it gives peace.
