Beyond what Christ said according to scriptures, what further "proof" would you need? We know that +Ignatius of Antioch believed in the Real Presence. We know that the 2nd century anaphorae of The Church certainly appear to teach the Real Presence. It is also apparent that there were people running around at the end of the 1st century and into the 2nd who didn't believe in the Real Presence, but that understanding of scripture seems to have faded away until after Luther. In any event, what would scripture have to say to convince you that Christ meant what he said?

Well, John and Paul for starters...
1Th 5:9 For God has not destined us for wrath, but to obtain salvation through our Lord Jesus Christ, "
