God never intended for us to be left to pray on our own. God never changes His purpose, but He often does purpose a change.
John OwenChrist by his death destroying the works of the devil, procuring the Spirit for us, hath so killed sin, as to its reign in believers, that it shall not obtain its end and dominion.

John OwenI have known some good men who have been so addicted to their study, that they have thought the last day of the week sufficient to prepare for their ministry, though they employ all the rest of the week in other studies. But your business is to trade with your spiritual abilities. ... A man may preach a very good sermon, who is otherwise himself; but he will never make a good minister of Jesus Christ, whose mind and heart are not always in the work. Spiritual gifts will require continual ruminating on the things of the Gospel in our minds.
John OwenThe Scripture abounds in commands and cautions for our utmost diligence in our search and inquiry as to whether we are made partakers of Christ or not, or whether His Spirit dwells in us or not-which argue both the difficulty of attaining an assured confidence herein, as also the danger of our being mistaken, and yet the certainty of a good issue upon the diligent and regular use of means to that purpose.
