What day should we be rejoicing over? The popular chorus has us rejoicing merely because it is today. To me, that is just taking words out of their context. The text appears to give us two other options. Either we should rejoice in the day of rescue, or rejoice in the festival day when the rescue is remembered. Either way, the rejoicing is not just a party looking for a place to happen. It is a call to celebrate grace. The day of grace is the day that the LORD has made. Jesus entering Jerusalem as its king was such a day. His atoning death on the cross is another. His soon return will be yet another. Those were rescues to celebrate.
LORD, we thank you for your past rescues, and your future return. We will celebrate that rescue.
