1 Jn 1:6 If we
say that we have fellowship with him, and walk in darkness, we lie, and do not
the truth:
If we say that we have fellowship with Him but walk in darkness, if we walk in sin - then we lie and do not know the truth, nor do we do the truth.
For what is the truth - Jesus is the Way the Truth and the Life.
How can we fellowship with Him if we are dead in our trespasses and sins, for what does Life have to do with that which is dead? Nothing.
For the dead contaminate the living. The dead bring
disease and contagions. The Light can have no fellowship with that darkness,
that death. He is the only way to Spiritual life.
You can not fellowship with the dead, they can not talk to you of life, they can not know what you are experiencing, they can only bring death!
Jesus only can bring life.
So yes by their
walk, by their life you will know them and to whom they belong.
For if they are
filled with life, if they walk in the light, then they will have fruit and that
fruit shall be visible for all. What is that fruit we speak of? Works, changed
lives that spring forth from the Life and the Light shown in the life of the
Changed Christian.
Works are not necessary for Salvation, rather they are a sign of that Life and that Light.
