Ephesian 4:17 So I tell you this, and insist on it in the Lord, that you must no longer live as the Gentiles do, in the futility of their thinking.
This may seem a strange verse to read on the back of how God opened the gospel to all people, including the gentiles, but it has an important aspect!
The Jews knew they had God and knew they would ultimately go to be with Him when they died... the gentiles were yet to find the one True God!
We may cling to all manner of things in our lives in the hope we will have a better life, but the truth is the only special life we have will be with Christ after we die...
