“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 your always, to the end of the age.” – Matthew 28:19,20
The main reason why Jesus asked His disciples to “go” was because of John 3:16-17 “For God so loved the world, that he gave his only Son, that whoever believes in him should not perish, but have eternal life. For God did not send his Son into the world to condemn the world, but in order that the world might be saved through him.”
Harvest season is very short.
