A lesson from the season: סְפִירַת הָעוֹמֶר, Sefirat HaOmer, the Counting of the Omer. Do not worry if you are not familiar with this, that's the point! "Killing time..." "Wasting time..." or perhaps, "Counting time..."
Is the Lord really concerned with how we spend our time? Certainly, He commanded that we count days! Spend some time with me, and see what this is all about.
