Minnesota Pastor John Piper put it well when he said that “missions exists because worship doesn’t.”
When you read how Jesus commissioned his disciples to share the good news, there is this sense of urgency and necessity for us to be part of it, but there is also a progression in where we’re to be his ambassadors.
In Acts 1:8 he said, “and you will be my witnesses in Jerusalem, and in all Judea and Samaria, and to the ends of the earth.”
For the Jewish disciples, proclaiming the gospel in Jerusalem to God’s promised people was a no-brainer, but to go beyond that was news to them: Jesus had a wider scope for his message. What's interesting about these locations is that it begins local and from there goes international.
Your greatest mission field is your neighbourhood, your workplace – those you dialogue with on a daily basis but we shouldn’t forget that there is a call on all of us to be witnesses to the ends of the earth. Maybe this is with your prayers, and you’re giving if you can't get there physically, but to live on mission is to think local and global.
