We have been sent to the world, so we go (John 17). But we do not go empty-handed, like poor nomads with little to offer but friendship. We are ambassadors and we have a message. Simply stated, the message is the gospel—the good news of the life, death, resurrection, ascension, and glory of Jesus Christ, the Son of God. This gospel is not abstract truth. Jesus Christ died for sinners—all of us—that we might be forgiven by God and reconciled to God on the basis of Jesus’ substitutionary, atoning death. This indescribably profound truth is the ultimate basis for missions.
But there is no point in “going” if we do not carry and clearly articulate the gospel.
