At the close of 1644 the Long Parliament and the Westminster Assembly found themselves in a difficult position. The preachers had declared that, if they all did the will of the Lord in the church, He would surely bless the efforts of their army in the war against the King. But the church was still unreformed and the King undefeated. They could have peace at the risk of allowing Charles to regain control of the church. They could go on with the war at the cost of permitting religious differences among their own partisans to continue and spread. In other words, nothing could be settled so long as Charles kept the field and the fear of defeat hung over English and Scots, Parliament and Assembly, Presbyterians, Independents, and sectaries alike. The predicament was made to Cromwell's hand. The campaign of 1644, having ended in frustration, he returned to his place in the House of Commons and initiated the maneuvers which led to the reorganization of the army with Fairfax in command but in the event with Cromwell still as its driving force. The result was the victory the Assembly divines had looked for as the sign of God's favor upon their efforts to reform the church but victory on terms which made reform of the church as they conceived it more difficult than ever. For Cromwell's accomplishment in war and politics was due to his gift for drawing upon those very energies of the spirit in himself and others which had been evoked in the people by Puritan preaching but which the ministerial caste was now striving to keep within bounds. He had succeeded in organizing victory not by curbing and containing the Puritan spirit but by giving it free play among the men under his command and by granting scope to its most characteristic modes of expression and organization. Hence the preaching of the Word in the parliamentary army as reconstituted in the New Model had not a little to do with the army's military success.
