In the matter of fellowship God looks not at how much we apprehend of His will but rather at what our attitude towards His will is. If we honestly seek and wholeheartedly obey His desires, our fellowship remains unbroken, even though there should be many unknown sins in us. Should fellowship be determined by the holiness of God, who among all the most holy saints in the past and the present would be qualified to hold a moment's perfect communion with Him?
