John 16:7,8 (KJV)
7 Nevertheless I tell you the truth; It is expedient for you that I go away: for if I go not away, the Comforter will not come unto you; but if I depart, I will send him unto you.
8 And when he is come, he will reprove the world of sin, and of righteousness, and of judgment:
Allow the Lord to shine through you. This is His desire to use each one of us in a big way. We are all important to Him.
Is your lifestyle pleasing to God? You will know this if you are in His will or in sin through reading the Bible daily. The Word will speak to our life and convict us of anything wrong. The question is, are you willing to let God cut out the evil out of your life? I will say that it is so much better when the Lord God can dwell inside of us.
