There is a time to be silent and a time to speak.  Sometimes silence is the best witness.  Our incessant talking can have the undesired side effect of driving people away from the Lord we want them to love.  We are to be “full of the Holy Spirit and wisdom.”  When the fruit of the Spirit is present in our lives, the hungry are drawn to it.  Our witness is “dead in the water” when our lives turn people away from Christianity.  Live the words of your witness.  Be the kind of person that, when people know you, they want to know your Lord.
