Public acknowledgement of Christ comes in two forms.  One offered in answer to my faith and the other is my natural expression of my faith.  Neither is a planned or pretentious effort.  I don't schedule my acknowledgement of Christ.  I live it.  When another challenges or questions my faith, I have the obvious chance to speak of my Lord and His goodness.  But greater still is the natural habit of speaking about Him in my daily conversations and recognitions. Prayer before my meal and letting someone know that we are praying for them are easy and effective.  Think about how your conversations held with Him throughout the day.  Start including others in the expression of that and you will be amazed how His witness in your life grows.

Talk more about Him.  Michael.
