God makes very clear through His word that our faith isn't faith at all UNLESS it is proven through faith. We are not saved by our works, but rather, our works prove our salvation. Faith is necessarily linked to works. This matters because our testimony of Jesus transforming us is only valid if it can be seen by how we live. The more we exercise our faith, the stronger it becomes. And the stronger our faith is, the more we put on display the transformational power of Jesus.
