At church the other day, I noticed that a couple of the verses we read started with the phrase por tanto. I couldn’t reason out the meaning to myself. I knew that tanto was much or a lot and the verses just did not make sense with this meaning.
One of the verses was:
Por tanto, id, y haced discÃpulos a todas las naciones, Mateo 28:19
After studying the phrase I found that por tanto means because of this or for this reason. The verse makes much more sense now.
