Quote from : God in My Everything: How an Ancient Rhythm Helps Busy People Enjoy God Book

Our prayer life and rule of prayer will be shaped by the different stages of our spiritual journey as well. Many people who have just come to know Christ find that their words flow easily. Prayer is a joy for them. But, as with romantic relationships, there is a natural movement beyond this honeymoon phase. When feelings of intense connection with God ebb, we have a new opportunity to engage God - not based on cool spiritual vibes but as an expression of our genuine love for God. Times of spiritual dryness are normal for almost everyone, even if we haven't sinned and to the best of our knowledge haven't done anything to wall off our relationship with God. God may allow this dryness so that we can mature in our relationship with him and learn to seek him not for an ecstatic spiritual experience but out of a deeper love and commitment.
