Or miry places are marked by an illness that won't be cured, bills past due, disrupted family lives, or being charged with a wrong not vindicated. God doesn't abandon you there. This is not a period at the end with no hope. Something is working in that miry place. Salt, which heals when in proper proportion, leads to promising outcomes.
Salt makes for a tougher skin, and it takes tough skin to handle urban ministry.
You need to get salted down real good. God balances things. You need a little miry place to appreciate the meaning of life. You learn special graces in miry places. In miry places you find out who your friends are, and you discover the faithfulness of God.
