Acts 1:8  You shall receive power when the Holy Spirit has come upon you; and you shall be witnesses to Me in Jerusalem, and in all Judea and Samaria, and to the end of the earth.

A story is told of a little girl who turned to her mother on the way home from church; she said, "Mommy, the preacher's sermon this morning confused me." 

The mother said, "Oh! Why is that?" 

The girl replied, "Well, he said that God is bigger than we are.  Is that true?" 

"Yes, that's true," the mother replied. 

"He also said that God lives within us. Is that true too?" 

Again the mother replied, "Yes." 

"Well," said the girl. "If God is bigger than us, and He lives in us, shouldn't He show through?"

So how do you know that “the Holy Spirit has come upon you,” and “God is showing through?”   Do as Jesus said, “ask,” “If you then, being evil, know how to give good gifts to your children, how much more will your heavenly Father give the Holy Spirit to those who ask Him!”(Luke 11:13) If you have “asked,” then you have received; the only ‘proof’ you need is God’s promise, “your heavenly Father [will] give the Holy Spirit to those who ask Him.”  Either you believe Him, or you don’t!!!

My friend, I want you to understand that much of the world is not interested in that black book you carry, called the Bible; there is no use beating them over the head with it.  The only Bible some unbelievers will read, is ‘you.’  Is Jesus showing through?  Are you a “witnesses for Jesus, to the end of the earth?”

You, as a Christian, should be living in such a way that will provoke curiosity in the unsaved.  The “power” Jesus promised, will enable you to live in a way that they will come to you and ask, “What makes you tick?”  Then, you can say to them, “Ah, let me introduce you to The Man!”  Then, and only then, will God’s Word make sense to them.

By living in a manner that Jesus “shows through,” you will open the door of opportunity to witness to the unsaved.  A holy life will produce the deepest impression; lighthouses blow no horns, they only shine.  Remember that you are called to be a witness, not a lawyer. 

My friend, a living Jesus, in a living man, is a living sermon; what kind of a sermon are you preaching?   You would be well advised to trim your lamp more often, so it will give off less smoke, and shed more light.  Remember it is your pastor's job to fill the pulpit, it’s your job to fill the church. 

Now I’m going to get down where the rubber meets the road and I want you to be honest with yourself, remember, you’re not fooling God.  Are you a “witnesses [for Jesus]?”  Do you have a burden for the lost, or have you lost the burden?
