Every Christian has direct relationship with God and can receive edification straight from Scripture, worshipping together with His people and finding in the Word of God food and spiritual medicine for the health of his soul.
Yet sometimes a man experiences problems which are difficult for him to solve by himself; when usual remedies do not seem to work (Gal 6:1). Then the time comes to seek a deeper and more intensive help of mature Christians in order to solve the problems which hinder his personal growth and life of faith.
