This has been a recurring theme ever since I went to a seminar on hearing God's voice a couple winters ago.
We must hear God's voice or we are lost.
How will we know the way to the job where we belong, the church we belong to, the people we belong to, the things we should be doing, as opposed to the things which are frivolous?
Jesus said, "my sheep hear my voice." This is what distinguishes us as his sheep - that we hear him, and then follow him.
