Then Jesus came to them and said, “All authority in heaven and on earth has been given to me.  Therefore go and make disciples of all nations, baptising them in the name of the Father and of the Son and of the Holy Spirit,  and teaching them to obey everything I have commanded you. And surely I am with you always, to the very end of the age.”

Matt 28.18-20

Reading the following comments from David Platt on these verses made me realise that I have run out of fuel. I needed to read this to remind me of why we go- or maybe more accurately why we stay! And it's so encouraging to hear the reality- we are on the front lines, and yes it is a battle- why does that surprise us? But how wonderful that the Lord Jesus is in the driving seat, empowering, directing, providing and guiding.

Platt:

His worth is the fuel of our mission. In other words, we go because Jesus is worthy of the worship of every person on the planet. Our Savior deserves all praise (Rev 5:9-10), so we long to hear all people confess, "Jesus is Lord!" This also reminds us that His worship is the goal of our mission. Followers of Christ live for the day when every tribe and tongue and people and nation gather around our God to give Him the global glory that He is due (Rev 7:9-10).

His mission will succeed because His authority guarantees it. After Jesus spoke His final words to the disciples, He ascended to heaven (Acts 1:9) where He now sits at the right hand of the Father. Now in His exalted position, Jesus empowers His people, directing, guiding, and providing them with everything they need to bring this mission to completion. Matthew 24:14 is a guarantee: "This good news of the kingdom will be proclaimed in all the world as a testimony to all nations. And then the end will come." We are on the front lines of a spiritual battle that is raging for the souls of men and women around the world, and the all-sovereign Son of God, our Savior, is in command of a commission that will be accomplished.
