A baker is not a mechanic.  The president is not a janitor.  A banker is not a policeman.  A preacher is not a truck driver. 

Each one has a specific task given.  If the task receives everything that can be given, it will consume enough energy and time to accomplish well. 

Some are given to give.   Some are given to teach.  Some are given to preach.  Some are given to heal.  Some are given to testify.

Don’t let others urge you into doing something God has not given you to do.  But do what He has given you with all the energy He gives.  Let God be God.  You are only a servant.

By His Grace.
