The Voice of the World and True Fellowship

I just read in my personal devotions 1 John 3 and 4.

In chapter 4:5, it says, "They are of the world. Therefore they speak as of the world, and the world hears them."

When people speak from a world's perspective (the philosophy of living that is antagonistic toward God), what does that say about those people?

Does that mean that their heart has been captured by the world?

The person who speaks from a worldly perspective reveals that his/her heart has a disposition toward, affinity toward, and affection for the world. Does that mean that person belongs to the world?

Didn't Jesus say in John 10:27 - "My sheep hear my voice, and I know them, and they follow me"

Have we sought to blur the lines of distinction (that the bible does not make) between Christian and non-Christian because we don't want to truly come to grips with the lack of love, affection, and affinity for Jesus in our own hearts?

What about those whose lives are marked by affection for the world? Are we, as a body of Christ, willing to speak the truth in love to them, or will we continue to let them live life with, maybe, a false assurance of their salvation?

We have lost the true biblical understanding of fellowship and community--the mutual accountability and love for one another.

We think that as long as we are all "getting along" and there is no "major drama" going on, everything must be OK.

Yet, the hidden sins of the heart go unchecked because we don't want anyone to dig deep into our lives because it's none of their business.

How sad that we don't have real fellowship and love as we strive to love Jesus and show that love in word and deed to a dying world.
