One thought on “Comparatie intre Book Readere”
  1. I want to thank God for what he’s done in my life thus far. I graduated from the unevirsity in 2008, with the dream of doing my Masters abroad but it wasn’t forthcoming. I applied to a unevirsity in Canada in 2011 but my application was turned down. Later that year when I was seeing if I could apply to other universities for admission in 2012, the spirit of God told me to mail that same school that refused me admission earlier in the year, which I did and to my greatest surprise, the school replied and were asking me are you still interested in coming?, just reply yes and we will send your admission letter . I couldn’t believe it, with the speed of light I replied yes and that was how I got admission with funding attached.This testimony was borne out of the fact that I made a pledge that if God can grant me a Visa I will testify to his goodness in my life. When I filled my application for the Canadian Visa, somehow I omitted a very vital document that without it one’s application was going to be returned, but I prayed to God and he had his way, before I knew it, I was called up for medicals and in the month of grace, I received grace from heaven and my Visa was issued on the 31st of May .I didn’t get to know this until the 15th of June when I was asleep and I felt so restless in the night,something led me to prayer after which the spirit led me to track my Visa application, I broke down to tears when I found out it had been ready for pick-up, with the conviction in my heart that the lord had done it. On getting to the pick up centre on June 18th, lo and behold my Visa was there to welcome me I am now in Canada for my M.Sc program, Praise ye the Lord!!!!!!
