It is the experience of all Christians that the moving’s of God's Spirit comes and goes, and when He is gone, it leaves us feeling poor and beggarly. Paul addresses this in Galatians 3 and I included a piece from Martineau that also gives his spin on it.

"You foolish Galatians, who has bewitched you, before whose eyes Jesus Christ was publicly portrayed as crucified? 2 This is the only thing I want to find out from you: did you receive the Spirit by the works of the Law, or by hearing with faith? 3 Are you so foolish? Having begun by the Spirit, are you now being perfected by the flesh? 4 Did you suffer so many things in vain—if indeed it was in vain? 5 So then, does He who provides you with the Spirit and works miracles among you, do it by the works of the Law, or by hearing with faith? Gal. 3:1-5

"It is confessed by the anxieties of many good minds, that are ashamed of the slow fires and faint light of their faith and love; that they can spur their will, more easily than kindle their affections; and wish they were called upon only to do, and not also to feel. They cast about the vaguest and vainest efforts after deeper impressions of things holy and sublime: they wonder at the apathy with which they dwell amid the infinitude of God: they convince themselves how untrue is the state of mind which treats the "seen and temporal" as if there were no "unseen and eternal;" they assure themselves how terrible must be the disorder of that soul, whose springs of pure emotion are thus locked in death. But with all this they cannot shame, or reason, or terrify themselves into any nobler glow: the avenues of intellect, and judgment, and fear, are not those by which a new feeling is permitted to visit and refresh the heart. The ice cannot thaw itself; but must ask the warmer gales of heaven to blow, and the sun aloft to send more piercing beams. There is nothing vainer or more hopeless than the direct struggles of the mind to transform its own affections, to change by a fiat of volition the order of its tastes, and the intensity of its love. Self-inspiration is a contradiction: and to suspend, by upheaving’s of the will, the force of habitual desire, is no less impossible than by writhing’s of the muscles, to annihilate our own weight."

So, the method to rekindling the Spirit now, is the same as in the beginning, by humbly crying out to God to re-manifest Himself to us by the earnest prayer of faith.
Oh, taste and see that the LORD is good. 

Oh, the joys of those who take refuge in him!
