Church is composed of people–other very flawed human beings.  The only thing a church can do is to demonstrate the love of God although it is not the church who does that.  It is really individuals who demonstrate love.  It is always done one on one.  Jesus taught his disciples one on one.  In fact He did more than that:  He transmitted love.  Your talk does not matter if love is not demonstrated in your life.  Truth is not enough.  Ultimately each person wants to be loved.  That is the only way one truly can find out about the all encompassing love of Jesus–not from the church but through individuals who chose to love the people God puts in front of them.  Thus, I hate religions who over and over claim to know the only way.  There is only one way you can find about the love of God–through contact with an individual who lets the love of God flow through his/her spirit and chooses to love the very flawed people who He puts in his way.  Love is the only thing that matters.  Forgiveness is embodied in love.  He died for you.  Only you.  And only another individual can transmit that to you.
