I believe a spiritual leader should encourage his/ her family to pray and study the bible every day. meaning as an individual in the family we should have devotion with God in daily basis, in order for spiritual growth to take place in our walk with God. the realistic strategies to use and to help the family grow, is to read a certain portion of the bible every day and memorize the key scriptures. and also, by attending bible studies and other church activities in the church that promote scripture reading.
A spiritual leader might not lead by example sometimes, because it might not be something who doesn’t stay with the family in the same house.so that person can easily say something and do the different thing. while vocational ministers can only be focusing on getting paid and never mind about the congregation’s spiritual health or spiritual growth.
Most of the time you will find that vocational ministers manipulate the church of God to enrich them by giving them personal offerings and personal belongings. that means that if a spiritual leader fails to take care of his / her family, he will also fail to take care of the congregation of the Lord. and when a spiritual leader takes a good care of his / her own family the congregation will also be blessed and will be looked after with good care.
