Sunday marks a big event for the pro-life community but it depends on churches making a difference.
The event is the annual Life Chain, which calls on Christians in America and Canada to line busy streets holding signs that celebrate life and oppose abortion.
Royce Dunn, who heads National Life Chain, says the Church is the only hope pre-born children have.
"And certainly we want to receive God's ministry to us," he says, "that we can be the very best witnesses we can be just in prayer and solemn meditation there on the sidewalk."
For decades it's been the laity leading the charge to protect the lives of the preborn, but Life Chain is calling on pastors to lead their flocks to the public sidewalk and take part, too.
God expects the leadership of the pro-life movement to be the "shepherds" of the Church, says Dunn.
