Read Psalm 5:8 

God's voice isn't all that difficult to hear. In fact, you almost have to be closing your eyes and stopping your ears to miss it. 

He sometimes shouts through our pain, whispers to us while we're relaxing on vacation, occasionally He sings to us in a song, and warns us through the 66 books of His written Word. It's right there, ink on paper. 

Count on it—that Book will never lead you astray.

In addition to His unfailing source of wisdom, He has given you wise counsellors, friends, acquaintances, parents, teachers, and mentors who have earned your love and respect through long years. Screen what you believe to be the will of God through their thoughts, their perspectives. Does your conviction about the direction you're headed grow, or are you seeing lots of red flags and caution signs? 

Before you undertake a major life-direction change, be very careful that it is God's voice, that it is God's call you are hearing.
