The idea of biblical accountability may be a new idea to them. They may find it to be a somewhat awkward and uncomfortable practice at first. To me, that fact best explains the epidemic in the 1970s and the 1980s of moral defection and marital failures among those in vocational Christian service. It is one thing to soar high and alone as an eagle, above the level of mediocrity. But it is another thing entirely, to be so alone that we encounter winds we cannot handle.
Accountability provides protection, growth, fellowship and encouragement.
Satan's attacks are subtle, and stress can be heavy. Such checking back is a form of accountability. Accountability and caring relationships are a form of loving my brother, my nearby neighbor, enough to hold him or her to God's standard. Accountability relationships in the Bible include that of Saul the king to Samuel the prophet, Nathan holding king David accountable for moral failure, Nehemiah wanting to travel to Jerusalem and rebuild the walls but being accountable to King Artaxerxes, Daniel to his God, Jesus to His Father, Paul and Silas to the church at Antioch, Timothy to Paul, etc. An unhealthy choice would be to choose someone you know will tell you just what you want to hear, or someone who has the same weak areas you do.
