"If anyone does not obey our instruction in this letter, take special note of him. Do not associate with him, in order that he may feel ashamed. Yet do not regard him as an enemy, but warn him as a brother." NIV translation
Now, Paul gives specific instructions on how to deal with the lazy Christian. He tells the believers to in effect shun the brother in hopes that he will be ashamed and repent. Paul also reminds them that they should not treat him as an enemy since he, too, is their brother. One of the biggest problems today in the body of Christ is that we often forget the last part of this instruction and treat those that we do not agree with as enemies.
"Now may the Lord of peace himself give you peace at all times and in every way. The Lord be with all of you." NIV translation
Paul begins to close his letter to the Thessalonians by reminding them that peace comes from God and asking for the Lord to grant them that peace.
This is a good reminder for us today as well with all of the turmoil in the world. There is much talk of peace and peace negotiations but no mention of the Prince of Peace which is the source. We must be wary of anyone that hopes to bring peace to the world without Jesus Christ because it is not possible.
"I, Paul, write this greeting in my own hand, which is the distinguishing mark in all my letters. This is how I write." NIV translation
At first, this verse may seem kind of strange as Paul reassures the people that he has written this letter but we must remember that there was a false report being circulated among the believers there. Paul, is basically telling them that they can recognize his writing because it has been consistently based on the teachings of Jesus Christ. This also is a reminder that Paul stayed humble even as God used him to start the greatest spread of the gospel that the world has ever seen. Even with all that going on, Paul wrote this letter "in my own hand" instead of getting someone to do it for him. Today, there are many who start out humbly serving the Lord but when the blessings come they forget the humility. We should remember that God will lift up the humble and the proud will be brought low.
"The grace of our Lord Jesus Christ be with you all." NIV translation
Paul closes this letter with the prayer that God's grace would be with them. Paul was a man that deeply understood grace because of his life before he accepted Christ. He wanted them to also understand the extreme nature of that grace and the fact that it is sufficient for all things.
