1:6-7
6: And you became imitators of us and of the Lord, for you received the Word in much affliction, with the joy of the Holy Spirit
It can help us if we find other more mature Christians who follow God and learn from them. They can often teach us things that we need to know and help us learn how to go through our trials. Ultimately we imitate Christ and imitating Him precedes how we imitate others. Paul was driven out from Thessolonica due to persecution so his mention of them receiving the Word in affliction makes sense. However, they had the joy of the Holy Spirit which aided both in imitation and during their afflictions.
7: so that you became an example to all the believers in Macedonia and in Achaia
We are always influencing the people around us. Just as the Thessalonians were influenced by Paul, Silas, and Timothy, they are now influencing other believers not only in Thessalonica, but also in the surrounding areas.
As Christians, we need to realize the influence that we have on those around us. If we are Christians, yet have a spiteful and vengeful attitude towards others, that is not showing the Gospel and will negatively reflect on Christ and fellow believers. I’m sure we all can think of at least one person who claims to be a Christian yet affects others negatively. Instead, we need to seek others who can be good examples to us and imitate them. Ultimately our goal is to imitate Jesus and He gives us people who can help us with that (as well as His Word and prayer.) We should seek to be good examples to others and point them to our glorious savior Jesus Christ! I know none of us are perfect, but if our focus remains on Christ, people will be able to see Him, even when we stumble.
