but test everything; hold fast what is good. Abstain from every form of evil.
English Standard Version (ESV)
Paul is wrapping up his letter to the Thessalonians, encouraging them to live lives that honor God as they await Jesus' return. He's just given them a series of commands about discerning God's will and living righteously, so here he's telling them how to approach all the different teachings and ideas they'll encounter, urging them to critically examine everything and cling only to what is true and good.
Paul doesn't just tell us to believe; he tells us to test. What does that mean for our faith today?
The Command to Discern
The instruction 'test everything' isn't about being cynical or judgmental. It's a call to active, thoughtful engagement with spiritual teachings and ideas. In the ancient world, as now, false prophets and deceptive teachings could lead people astray. Paul equips the Thessalonians (and us!) with the vital skill of discernment.
It's About Wisdom, Not Distrust
Think of it like quality control. When you buy something, you check it to make sure it's what it's supposed to be. Similarly, we are to examine teachings against the standard of God's Word and the character of Christ. This protects us from error and helps us grow in true understanding.
After testing, Paul gives a clear directive: cling to what is true and beneficial. What does this tenacious grip look like?
Clinging to the Good
'Hold fast what is good' is the positive counterpart to testing. It means to keep, to retain, to obey, and to remain steadfast in what is proven true and life-giving. This isn't a passive agreement but an active commitment.
Rooted in Truth
What is 'good' here? It refers to teachings, practices, and truths that align with God's character and His revealed will in Scripture. It's about embracing the solid, life-affirming core of the Gospel and Christian living. Holding fast means letting these truths shape our lives, our choices, and our perspectives, even when it's difficult.
