I recall when I visited VIO office to renew my Driver's Licence, an officer set a test for me and the idea was to find out if I understand the road signs. At first, I was embarrassed, I decided to calm down and attempted the questions with common sense, incidentally it was evident that I got most of the meanings of the road signs.I have also cultivated the habit of attending midweek services, our beloved pastor Adefaratihandled this topic, 'Christian service', while he ministered I remembered my experience at VIOheadquarters as explained in the first paragraph, it downed on me that it's possible to developservice codes in form of signs, this would remind us of our commitments in the vineyard.
