The snow changes everything! No matter how old we are, there's something amazing about it, eveywhere looks more beautiful, fresh, clean. The Lord uses this picture to tell us something amazing, using his prophet Isaiah - 'though your sins are like scarlet, they will be a white as snow' (Isaiah 1:18). The people in Isaiah's day were religious (1:11-15), but their hearts were far from from God, they had forsaken the Lord (1:4) and not listened to his teaching to the point that they are compared with Sodom (1:10). Such a wicked people will surely be abandoned by the Lord, and yet, there is the promise of grace, of forgiveness, of a fresh start, though their sins are like scarlet, they shall be as white as snow. How will this fresh start happen? Isaiah tells us later in 53:6, that all our sins will be laid on the servant who will be punished in our place, the Lord Jesus Christ.
It's the sort of news that made the apostle Paul willing to face prison for sharing it, and in Acts 16 (one of the readings from the M'Cheyne reading plan for today), it's the kind of news that leads to Paul and Silas singing hymns of praise to God even while in prison. It's the sort of news that changes even a tough Philippian jailor.
So as we enjoy the snow today, let's remember and give thanks for God's incredible rescue through Jesus, that though we have forsaken the Lord in many ways, if we have trusted in Jesus, we are completely forgiven, washed clean, just like the snow that covers everything. No matter what we have done, it can be completely forgiven by Jesus, praise God.
