The marks of true Christianity……True Christianity leaves marks ├ö├ç├┤ evidence of its presence in the soul. And the people of the world notice when it isn’t there.……Unbeliever oftentimes decide whether or not to accept a teaching not so much on propositional arguments and Biblical proof , but rather on seeing “success” in the lives of those who have submitted themselves to that teaching. …Josh Mc Dowel asked students he worked with who claimed to be unbelievers, if they would become Christians if he presented iron-clad evidence that the gospel was true and found that their responses started out as… 'yes’, but then went to 'no, not really’ as they admitted to him that their real deciding factor for believing was an evidentially reasonable proof: …Show me how this can change my life; …Let me see someone else who has found that it works for them.” …and let’s see just how authentic these Christians are, …and if they walk the talk, then I’ll actually consider the faith. …They want to see true Christianity, in the lives of true Christians.……In essence, then, you and I as Christian becomes the only gospel or Bible some unbelievers will ever “read”. …When the non-Christian sees a mismatch between the little that they have heard about the teachings and life of Jesus and His professing followers, they naturally get confused at first and then without even realizing it (if their experience persists with other supposed believers), they give Christianity an “F” in the test and walk away.……True Christianity does not preach a salvation by works, but it does preach that works will be evident if one's faith is sincere. …This is what the Apostle Paul drives home to his readers in the second chapter of Romans. …He asks his audience if they boast in God and if they think they’re a shining example to others who just don’t seem to measure up to them, then they need to do a quick self-examination. …Do they break the very things they say others should follow? …Are their lives consistent or opposite to what God’s Word says? …If so, Paul says,

Rom. 2:24

No wonder the Scriptures say, "The Gentiles blaspheme the name of God because of you."

In other words, the poor behavior of the Christians in Rome reflected back on the Creator in a very negative way, and this Paul, writes is a very negative thing.…But when believers obey, act and conform to Christ’s defining mark then the unbelieving world is impacted in a positive way. As he says in John 13:35

Your love for one another will prove to the world that you are my disciples.
