Jesus left the Church with the responsibility:
"Go ye into all the world and preach the Gospel to every creature." (Mark 16:15)
He equipped believers with the power to accomplish the task:
"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." (Acts 1:8)
We have work to do...
