But where in the Bible is missions ever identified as an optional program in the church? We have just seen that we were all created by God, saved from our sins, and blessed by God to make his glory known in all the world. Indeed, Jesus himself has not merely called us to go to all nations; he has created us and commanded us to go to all nations. We have taken this command, though, and reduced it to a calling— something that only a few people receive.
I find it interesting that we don’t do this with other words from Jesus. We take Jesus’ command in Matthew 28 to make disciples of all nations, and we say, “That means other people.” But we look at Jesus’ command in Matthew 11: 28, “Come to me, all you who are weary and burdened, and I will give you rest,” and we say, “Now, that means me.” We take Jesus’ promise in Acts 1: 8 that the Spirit will lead us to the ends of the earth, and we say, “That means some people.” But we take Jesus’ promise in John 10: 10 that we will have abundant life, and we say, “That means me.”
In the process we have unnecessarily (and unbiblically) drawn a line of distinction, assigning the obligations of Christianity to a few while keeping the privileges of Christianity for us all. In this way we choose to send off other people to carry out the global purpose of Christianity while the rest of us sit back because we’re “just not called to that.”
