Isaiah 11 is a good cross-reference for this text of Isaiah 53:2-3. The idea of a root coming out of dry ground or a stump is repeated several times in Isaiah and New Testament writers pick this up.
Dry ground is a clear reference to humanity. Adam means literally "dirt man." Dry ground is a reference to fallen or failing humanity. Paul says just as through one man, Adam, all die, so in one man, Jesus Christ, all will be made alive.
What a powerful irony this is! A little tender shoot coming out of dry ground that seemed insignificant. People didn't think he was important at all. Yet, he saved mankind!?
Yahweh, our hearts can resemble that arid desert ground, cracked and good for nothing. Grow in our hearts and break through like a tender root in the dry ground of humanity.
Fast from something that takes your attention off of creation and as Spring comes, notice each new day's handiwork of God. Each day there is something new in the region where I live in Oklahoma. A few days ago it was the Bradford Pears blooming white and the daffodils below them. Yesterday it was the Redbuds, the Oklahoma state tree, and Cherry Blossom trees. Today it's the Crocus below and the Crabapple tree blossoms above. The weeds are here, too!
Spend less on your yard so you'll have more for humans in need. I may have already mentioned this in an earlier post, but I realized a few savings on my yard by doing some things differently, and in some ways I experience a few more weeds, but that's OK. Are we meant to live on golf course grooming while the world is hungry? Find something to give up today, so you'll be more ready tomorrow (metaphorical tomorrow, future) for helping the poor.
