These two questions are two that I have been hearing from my friends and family in the last week...my response:
I am far from a good person, in fact, the bible says there is none that does good, not one. I can do nothing good by myself...it is God working through me. If it were up to me I would sit around being self centered and lazy, it is only by God's love for me that I can love others.
As for being crazy...
If I believed that this life was all there was, then yes, giving up my job, my house and my life would be crazy BUT I don't believe that this world is all that God has for me. I am serving him now and giving up my worldly things for treasures stored up for me in heaven... I am thinking of my eternal future not my worldly gain.
As a Christian than...giving up my things now and serving God is the only thing that makes sense...its staying where I am and ignoring God that is the CRAZY and RISKY thing to do.
