Please make sure you are speaking the word, and not your opinion.  This is so important in the todays culture - our youth, and even some of our adult "christians" are confused.  God doesn't NEED us to add lights, video or the wow factor, just speak the WORD! (I am not saying all that is wrong, unless it is??)  God's word alone convicts, and redeems.  It is ABSOLUTE TRUTH.  

Hebrews 4:12 "For the word of God is living and active, sharper than any two-edged sword, piercing to the division of the soul and of the spirit, or joints and marrow, and discerning the thoughts and intentions of the heart."  

Blessings to you!
