Watch yourselves, so that you may not lose what we have worked for, but may win a full reward (2 John 1:8).
John's message does not just involve them "out there"; he is quite concerned for those to whom he writes. They must be careful to maintain the truth of God in Christ lest they lose their standing before God! The goal is the full reward of the resurrection of life. Let us strive to obtain it to God's glory!
