I know many sincere, devoted warm Christians who have never personally guided someone to repent and accept Jesus Christ as their Lord and Savior. Yes, they have talked to the unsaved about Jesus. Yes, they have given them tracts about Christ. Yes, they have invited them to Church. Yes, they have followed up on them subsequently. Yes, they have confessed to them about their struggles. Yes, they have listened and patiently answered quetions. However, the person did not give themselves to Christ...and never did. It frustrates Christians because they try so hard. Sometimes they feel inadequate compared to others who find success, and they often feel that they are letting God down. They're concerned about being so "unfruitful" that God may not accept them into heaven. If you never led anyone to Christ directly, would God not let you in?
