Whereby, when you read, you may understand my knowledge in the mystery of Christ)…
Charles G. Finney used to discover that sometimes his preaching was mighty in its influence to convict and convert sinners. At other times he seemed to be firing only blank cartridges. The results depended entirely upon his own spiritual condition, upon his nearness to or his absence from God. When he was in close communion with God the currents of power were mighty and irresistible. When his connection with the Lord ceased, either through unbelief or unworthy living, his lifting power was gone. Drawing nigh to God was invariably the most effectual way to draw the impenitent.
