Ephesians 4 "Weakness"

The last part of this chapter talks about how we should turn our weakness into a strength for the Lord as to better make sure it is no longer a weakness.  If you are getting good grades in all your classes except math, does it make sense to study spanish even more and hope your math grade gets better?  So my response to this is to give more and more so that I do not value earthly things, I can value only what is important.  I often am reminded that it is easier for a camel to fit through the eye of a needle than it is for a rich man to get into heaven.
