Pastor Alberto Williams shares "Anchoring a Heart" in the Language of the Heart: Faith Sharing New Testement series. 

It is the responsibility of a Christian who is sharing their faith to pray for the decision maker both while they are making the decision (perhaps even as they make it) and following the decision.  The job of sharing your faith does not end at the point of decision.  You can’t speak effectively about God if you don’t first speak intimately to God.
