Evangelism is what we are all called to do by God in the Bible. In the book of Matthew it states "Go ye therefore and teach all nations, baptizing them in the name of the Father, the Son and the Holy Spirit. Teaching them to observe all things and Lo I am with you always even even the end of the earth "(Matthew 28: 19-20)
So the text begins
"Go Ye"
Who is ye? Ye translated in to modern English is You so we are now clear who the text is aimed at (that means everyone just to clarify). Then it says
"Teach all nations"
So this does not mean skip past the Muslim "s or Buddhists" or those are Atheists, ALL means what it says, all, so no one is exempt. Next it says
"Baptizing them in the name of the Father, the Son and the Holy Spirit".
This means that we have to walk the full mile on this we have to let people know about baptism and its importance. We can not just say hey Jesus loves you and that "s it the job is done, we need to give some more information so people are aware what option they have.
Teaching them to observe all things
We have to give them the whole picture of what God is telling us and how best we can live our lives. In other wards we have to let people know what other lifestyle choices are available, what are the other ways you can live your life. Other principals and standard they can adopt.
"and Lo I am with you always even to the end of the earth"
Now this is the part that a lot of people forget. God does not send us to do something and then leave us to get on with it. The verse ends with the assurance that he is with us each and every step of the way.
