What kind of fruits do we bear?

There are these two lovely friends that I have recently made(Rhoda and Kelvin). We go to class together, do our assignments together and even share meals. They are not born again yet but they know a lot about the word of God because they were both brought up in church. So a few days ago, we decided to go out for coffee together. As we were just chatting over the cup of coffee, one of them said something that really made me do a deep reevaluation of my Christian life. She said that anytime she hears someone say that he/she is born again, she becomes so keen to watch them and how they conduct themselves. Do I have to explain how this left me feeling?

You see the bible in Matthew 7:16 says that you will know them by the fruits they bear. I remember my friend saying that evening that someone purporting to be born again should be a bible to those who have no bibles. And she was right in saying so. It is not enough to call ourselves Christians just because we read our bibles, attend church services, serve in ministries or pastor in a church. No. There are people who don’t go to church while others have no bibles to read. Others do not know the way of life and are living without a vision, in the confused ways of this world. These people can only learn through looking at us and seeing how we conduct ourselves.

What kind of fruits do we bear?
Isaiah 5:
1 I will sing for the one I love a song about his vineyard: My loved one had a vineyard on a fertile hillside. 2 He dug it up and cleared it of stones and planted it with the choicest vines. He built a watchtower in it and cut out a winepress as well. Then he looked for a crop of good grapes, but it yielded only bad fruit. 3 "Now you dwellers in Jerusalem and men of Judah, judge between me and my vineyard. 4 What more could have been done for my vineyard than I have done for it? When I looked for good grapes, why did it yield only bad? 5 Now I will tell you what I am going to do to my vineyard: I will take away its hedge, and it will be destroyed; I will break down its wall, and it will be trampled. 6 I will make it a wasteland, neither pruned nor cultivated, and briers and thorns will grow there. I will command the clouds not to rain on it." 7 The vineyard of the LORD Almighty is the house of Israel, and the men of Judah are the garden of his delight. And he looked for justice, but saw bloodshed; for righteousness, but heard cries of distress.

I decided to do a direct quote of Isaiah just to show us how God feels about the kind of fruits we bear. When God created us, he expected us to have right fellowship with Him. However, we fell and sinned. He gave us a second chance by sending His son to die for us, we accepted him. He further gave us His word which was to serve as our guide. He then commanded us to use this word to speak it to others and show them the right way by following what it teaches us, to bear fruits and be an example to the world. However, we have failed. We are not good examples and our fruits are wild. It has become so hard to tell the difference between us and the world. We talk like the world, dress like the world and live like the world. Is it a wonder that God is destroying us together with the world?
