Most of us do not need to be convinced that we are called to share our faith in Christ with others. The thread of proclamation and mission is woven through Scripture. At the same time, a large percentage of those who claim to follow Jesus are not involved in sharing their faith.
There are many factors in our reluctance to enter into evangelism. We feel ill-equipped, intimidated, unsure of the response of others, etc. If we listen to our fears or hesitancies, we will likely miss out on the joy of investing the gospel in the lives of those around us.
