Many people have roles that are publicly visible. Many try to make themselves publicly visible or famous.

Some, on the other hand, are not comfortable to be publicly visible and prefers to be behind the scene. Others do not have the confidence to converse with strangers to convert them to follow Christ.

But God uses each and every Christian. We may or may not know our impact, but if we obey him, he can do his thing.

Think of the greatest person who we admire most. Do we know the name of her / his teacher? And the teacher of that teacher? And on and on? Most likely the answer is 'no'. But because of "unknown" teachers, we have great women and men in this world.

A teacher affects eternity; he [or she] can never tell when his [or her] influence stops.

~ Henry Adams

Most of us probably are not teachers. The point is that we may be "unknown", but if we follow Christ faithfully, God can use our life to make an impact - whether we know it or not.
