"For the Holy Spirit will teach you at that time what you should say"
There was a time when I received a call from a close friend of mine who works a job in "Corporate America." He asked for prayer. He was to give a presentation to a large group in the company that he worked with. This man is intelligent, wise, and very talented in many areas. However, public speaking, like many people, makes him nervous. As we prayed together, we prayed that the Holy Spirit of God would speak to him and through him. Yes, even in the workplace, if we rely on Him, He can calm our nerves, speak to our soul, and enable us to speak with boldness in any situation. This applies to all aspects of our lives whether it's at work, addressing a tough issue with a friend, or reaching out to others and sharing your faith. You don't have to do it alone. Rely on Him.
Jesus is speaking in Luke 12 of giving an answer when facing persecution. But, the even greater truth He is emphasizing is the dependance upon the holy Spirit. We were never intended, nor expected, to konw it all, have it all, or do it all. We are dependant beings. We are to rely upon the Holy Spirit, His wisdom, and guidance. At the right time, in the instant we need it, He will give it to us.
Even if you're quick-witted and unafraid of speaking in most any situation, your gift is inadequate. It can never replace the need you have for relying on His guidance. The moment you begin to rely on your talent alone is the moment you begin to decrease your openness to Him, to His voice, and to His direction in your life. Be open to learning to wait, to listen, receive by faith, and to apply with immediate obedience. Grab hold of this truth and you will see the pressures of fear and anxiety melt away.
