Romans 12:2 ASV

In the first part of Romans 12: 2 it states that "do not conform (follow) to the patterns (sin) of this world, but be transformed by the renewing of your mind." I think that God tells us to quit be followers of the world like world wants us too, but be transformed by renewing your mind and start leading people to the word of God. Then at the last part it states, "Then you will be able to test and approve what God's will is- his good pleasing and perfect will." In what i see in that verse is God likes us, after we transforme to a leader, test/ show the world what God's will is. So i ask you this one question, are you a follower or a leader?
