“I know a guy…”  These words often introduce a turning point in a difficult situation.  Maybe someone desperately needs a job and is introduced to a friend-of-a-friend who helps him get hired.  Maybe someone is being harassed and needs protection.  Or maybe someone is sick and needs a sympathetic specialist.  If you are a Christian, it is because someone introduced you to the One who saved you.  And once you are under the salvation and protection of the Good Shepherd, nothing and no one can separate you from His love!
