Right now!

If there’s an awakening and you come to your senses and you know something needs to be done and you think to yourself, "Tomorrow I will…" or, "Next week I’m going to…," that’s not the Holy Spirit. This was actually an awakening for me a few years ago, an AHA moment that came as I studied the Bible. I came to the startling realization that the Holy Spirit always says today. He never says tomorrow.—AHA Student Edition electronic edition
