“As the Father has sent me, so I send you” (John 20:21)
We, the church, have been sent. We have been given a task: to take the Gospel to all the world.
"And Jesus came and said to them, 'All authority in heaven and on earth has been given to me. Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all that I have commanded you. And behold, I am with you always, to the end of the age.'" (Matthew 28:19-20)
So how do we do this? By the power of the Holy Spirit!
"But you will receive power when the Holy Spirit has come upon you, and you will be my witnesses in Jerusalem and in all Judea and Samaria, and to the end of the earth.” (Acts 1:8)
