And her face was no longer sad

 
For we know that if the earthly tent which is our house is torn down, we have a building from God, a house not made with hands, eternal in the heavens. ² For indeed in this house we groan, longing to be clothed with our dwelling from heaven, ³ inasmuch as we, having put it on, will not be found naked. ⁴ For indeed while we are in this tent, we groan, being burdened, because we do not want to be unclothed but to be clothed, so that what is mortal will be swallowed up by life. ⁵ Now He who prepared us for this very purpose is God, who gave to us the Spirit as a pledge. (2 Cor. 5:1-5 NASB)

For indeed, in this house we groan, and in this tent, we groan.  Groaning can come from many different places and take many different forms.  In the Greek, it means to sigh, murmur, pray inaudibly. To pray inaudibly, when words just won’t do, when it just goes too deep.  That longing, that wound, that sin.  Groaning can be a deeper means of expressing ourselves without words.  I can think of one precious woman, who was misunderstood when she groaned and prayed without words, Hannah. Here’s a peek at that story:

¹² Now it came about, as Hannah continued praying before the Lord, that Eli was watching her mouth. ¹³ As for Hannah, she was speaking in her heart, only her lips were moving, but her voice was not heard. So Eli thought she was drunk. ¹⁴ Then Eli said to her, “How long will you make yourself drunk? Put away your wine from you.” ¹⁵ But Hannah replied, “No, my lord, I am a woman oppressed in spirit; I have drunk neither wine nor strong drink, but I have poured out my soul before the Lord. ¹⁶ Do not consider your maidservant as a worthless woman, for I have spoken until now out of my great concern and provocation.” ¹⁷ Then Eli answered and said, “Go in peace; and may the God of Israel grant your petition that you have asked of Him.” ¹⁸ She said, “Let your maidservant find favor in your sight.” So the woman went her way and ate, and her face was no longer sad. (1 Samuel 1:12-18)
Hannah was deeply distressed, and prayed without words, she poured her heart out to God, who alone could do the impossible.  God was the only one who could open her womb and give her that child she longed for.  She just emptied herself before Him.  I believe she cried until there were no more tears.  But notice what it says at the end, “and her face was no longer sad.” Only God can do that, take our burdens upon Himself, in such a way as to remove our sadness.  Confidence in a Good God, who does Good Things, for those who cry out to Him.  I love what The Book of Romans tells us about groaning in prayer

²⁶ In the same way the Spirit also helps our weakness; for we do not know how to pray as we should, but the Spirit Himself intercedes for us with groanings too deep for words; ²⁷ and He who searches the hearts knows what the mind of the Spirit is, because He intercedes for the saints according to the will of God.
(Romans 8:25-27 NASB)
Even the Holy Spirit groans when He intercedes for us.  O Dear Believer, pour your heart out to God, and God alone.  He alone knows the end from the beginning. He alone knows the deepest parts of your heart. And He alone can do something about it!
