Believers should seek to be pure in every facet of life. One might consider limiting this to the places he goes or the things he hears and sees, but purity demands a much greater focus. Believers ought to think on pure things (Philippians 4:8) with pure minds (2 Peter 3:1) and pure consciences (1 Timothy 3:9; 2 Timothy 1:3). In particular, believers should have pure hearts before the Lord (1 Timothy 1:5; 2 Timothy 2:22). A pure heart will lead to a pure conscience and a pure mind. A pure heart changes where a man goes, what he looks upon, and the things he allows to enter into his ears. Every Christian should strive to make sure that all things are pure.
The Thessalonian believers chose to willingly trust Christ as Saviour and to obediently become His followers. According to Paul’s account, these believers endured great difficulties because of their faithfulness to the Lord. Paul commended them for their patience and faith for enduring these persecutions and tribulations. Unfortunately, far too many Christians today are unwilling to live godly (2 Timothy 3:12) for fear that living the Christian life will bring persecution and ridicule. These believers in Thessalonica understood what it was like to have people scoff at them for their boldness in the faith. They understood what it felt like to be mocked and cursed for their unwillingness to compromise. This is why Paul praised them. They endured the persecutions and tribulations with patience and faith. The world needs more Thessalonian type believers in the church today.
