It is the responsibility of every Christians to go and minister the gospel of Jesus Christ.  We can do this through many different formats, but the most effective is simply "one on one". Nearly 85% of those converted come through the witness of a friend or family.

We are commanded through scripture to be witnesses.  It is not an option or something for only the ministry, but everyone that calls themselves a Christian is obligated to tell others of the love of Jesus.

Luke 14:23 And the lord said unto the servant, Go out into the highways and hedges, and compel them to come in, that my house may be filled.

In our duty as witnesses, God has not left us alone for He is always faithful and with our commandment to compel He has given us the power to change our world.

Acts 1:8 But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth.

What stands between us and reaching our world?  Is it money or resources?  Is it power and influence?  The biggest roadblock in reaching our world is us!  Our excuses and needs stand in the way of impacting our world with the gospel of Jesus Christ. 

I found a video online that speaks to what I am writing of today.  Although, some of the content is a little over the top, the principle is there and it speaks of it effectively.  You may also get a chuckle or two.  Enjoy.
