“He continues to act towards sinful men in the way that He does in the Bible story. Still He shows His freedom and lordship by discriminating between sinners, causing some to hear the gospel while others do not hear it, and moving some of those who hear it to repentance while leaving others in their unbelief; thus teaching His saints he owes mercy to none, and that it is entirely of His grace, not at all through their own effort, that themselves have found life. Still He blesses those on whom He sets His love in a way that humble them, so that all the glory may be His alone. Still He hates the sins of His people, and uses all kinds of inward and outward pains and griefs to wean the hearts from compromise and disobedience. Still He seeks the fellowship of His people, and sends them both sorrows and joys in order to detach their love from other things and attach it to Himself. Still He teaches the believer to value His promise gifts by making him wait for them, and compelling him to pray persistently for them, before He bestows them. So we read of Him dealing with His people in the Scripture record, and so He deals with them still. His aims and principles of action remain consistent; He does not at any time act out of character. Man’s ways, we know, are pathetically inconsistent–but not God’s.
