I remember my mom waking us up on Sundays and saying, "Come on kids, we've got to get ready for church." That usually entails showers, shaves, blow dryers, makeup, ironing shirts, breakfast, and brushing teeth. (Not all those are for me you understand.) We have to show up to church looking good, smelling good, and ready to worship.
What about spiritual preparation for Sunday? We don't think about that much but our Old Testament counterparts sure did. For them the day of worship was Saturday which they called the Sabbath. The Sabbath was actually a day of twofold emphasis; it was a day of worship and rest. The Hebrew day started at dark, which meant that the Sabbath actually started at dark on Friday night and ended at dark on Saturday night. Because they were not supposed to do any work on the Sabbath they had to be completely prepared by dark on Friday. Work done. Food in the crock pot. Miscellaneous details taken care of. There was almost a paranoia by devout Jews about getting ready for that day of worship and rest.
What if we thought that way? How would be prepare ourselves for the day of worship? What benefit might we gain from viewing Sunday as our day of worship and rest? How could we maximize the praying, singing, fellowshipping, and studying on Sunday morning? The possibilities are only limited by our imagination but let me throw this idea out; the best way to "get ready" for church on Sunday morning worship is to worship the Father all week long. If you read up, prayed up, discipled up, all during your week then Sunday will become a day of overflow from what you already been doing.
