1 Thessalonians 5:11 (NLT)
11 So encourage each other and build each other up, just as you are already doing.
In this verse Paul tells Christians to encourage each other by building each other up. The Greek word used is oikodomeo, which means to erect or built a house from the foundation up or to restore by building and repairing. Paul wanted the readers to understand they were not to just encourage those strong in their faith, but also encourage those who were weak.

There is a problem prevalent among the churches today. The problem is heresy in regards to the Gospel of Jesus Christ, which stands firmly on mercy and grace. The problem is humanity�s persistence to justify themselves before God by their works and performance. It is a battle fought in every human heart. It is a battle fought against the grace and mercy extended by God through His son Jesus. It is a battle that causes people to tear down those around them instead of building them. For you see if we allow works to rule in our life instead of grace then we want to make ourselves look and feel better. And how do we do that? By tearing down others and building ourselves up. Remember the grace you have been given and extend that grace to others. Do not let the need to justify our actions cause us to stumble and neglect the Gospel of Jesus Christ. Be encouraged that we might encourage each other.
