I am in the middle of reading three different reading plans from YouVersion (I rotate reading from one particular plan each day), and today in the Canonical Plan started the book of Isaiah. I put off starting the book for a week or two because of its depth and heaviness, but today was the day. This is one of my favorite Old Testament books, probably because it is one that I understand the least, but three verses really stuck with me, Isaiah 1:18, 19, and 20.

Come now, let us reason together, says the Lord:
though your sins are like scarlet,
they shall be white as snow;
though they are red like crimson,
they shall become like wool.

At first I just read that above and moved on. I love that “let us reason together,” but if we stop there we miss the point. There is a decision to be made for that statement to come to pass on our lives, and it’s from verse 18, “if you are willing and obedient,” and verse 19, “but if you refuse and rebel.”

The decision is for Christ, and without Christ, verse 18 will never come to pass. The word from the Lord is a simple, yet a profound, if-then statement. Our sins will be forgiven if we trust and obey. This of course is not a full and complete exegetical look at verse 18-20, but at the start of this Holy Week, the incredible fact of Isaiah and the rest of Scripture is it all points to the saving work of Christ, done on the cross, which we traditionally observe starting on Thursday with a Maundy Thursday prayer vigil (see last year) followed by Good Friday.
