Rehash, Rehearse or Celebrate

We spend most of our time either rehashing or rehearsing. Rehashing is to relive the past, going over and over again of what we did, or what has happened to us. This is a way of us tethering ourselves to the past, unable to move forward in our thinking. By default, it is the pain, shame and guilt or in other words the negative memories and experiences that the mind chooses to rehash.
Rehearsing is a way of living in the imaginary future. Perceptions of threats that are real or imagined engages our minds in emotional battles. The mind imagines situations, strategizes or even rehearses the sentences to speak in that imaginary situations.
There is a big problem in both these. It drains our energy for the present. Jesus knew this when he told his disciples 'do not be anxious how you are to speak or what you are to say, for what you are to say will be given to you in that hour' (Matt 10:19, ESV). The disciples in the first century were cross-bearers. The command, 'take up your cross and follow me' meant living with the prospect of arrest, imprisonment or even death daily. However, they should not spend their time rehearsing for that moment.
Nor should they rehash the evil that is done to them after the event. Their time is  not to be spent licking the wounds of the past. They have a great task in the present. That is to do the 'work the work of the one who sent them, while it is still day.' The energy for the tasks of the that present moment should not be dissipiated in any way.
The old song said: 'There's race that I  must run, there are victories to be won, give me power every hour to be true.' Power and grace for the moment is what we need. We need to conserve it too.
