How will you know them by their fruit?

  Embracing Christianity, and living your daily life in accordance to its doctrine changes every aspect of your life which the evidence is by the fruit you produce. 

   Also, mind you that fruits are not only produced when one is a Christian, because even a non-Christian can equally produce fruit certainly because life was created to produce and to reproduce life which the process of life reproduction is also a season of bearing fruit. 

  So, Knowing that both Christian and non-Christian can bear fruit, "who are those according to Matthew 7:16a that will know them by their fruits?" I do not think the scripture was referring to non-christian but to a Christian. 

  The term "know" is to be aware through observation, making inquiries, and gathering information. 

   My question is, what observation, inquiry, or information a non-christian can give about Christianity that he is not part of? 

  To answer the above topic question of how you should know them by their fruit is by being born again. Receiving salvation and the word of God first then distinguishing between the fake and real fruit will be very easy.

  John 10:14-15.

   Why not know God first, become part of him through his word, and with the help of the Holy Spirit you will know the kind of fruit that is expected of you and every true Christian to produce.
