What is a soul worth?

How much is a soul worth? Sometimes, I wonder this as I slowly learn Spanish. Is it worth the hours to someday communicate the gospel with those Acts 2:42 Ministries is teaching English to? But after reading the three parables in Luke 15, I see that the answer is an emphatic YES! Jesus came for each one of us making a sacrifice that none of us can really comprehend. So, I continue to press on knowing the price Jesus paid for every person.
