Jesus left orders for the disciples before he left. He told them to: "Go ye therefore, and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost: Teaching them to observe all things whatsoever I have commanded you: and, lo, I am with you alway, even unto the end of the word. Amen." Matthew 28:19,20
The name of the Father, the Son and the Holy Ghost is Jesus.
In Mark chapter 16 verses 15-16 Jesus left orders to, "And he said unto them, Go ye into all the world, and preach the gospel to every creature. He that believeth and is baptized shall be saved: but he that believeth not shall be damned."
If you soul has not been redeemed by the blood of the lamb before the life leaves your body, your eternal resting place will not be Heaven, but hell.
The purpose of the preached word is so someone can hear this message and repent of their sins before it is too late.
