When I think of great Mom's I think first of my Mother who is now with the Lord. My Mom was much like Hannah of 1 Samuel 1 who when I was born prayed over me on the diaper changer and committed me, her unexpected newborn, to the Lord to serve the Lord full-time. Her prayers brought me to Christ & to His service. Often when I woke early I could find her with her Bible open at the kitchen table praying. Like Hannah, mother's pray and their prayers are deep and effectual to the moving of nations and people for the Gospel. Hannah was embarrassed, fruitless, misunderstood and pitied. She prayed earnestly with words that could not be uttered. The Lord heard her plea and gave her a son whom she committed to God. Nothing to me illustrates better the groanings of the Spirit in Romans 8 than the fervent prayers of a Godly mother.
Here is Hannah's prayer & praise of victory:
"My heart rejoiceth in the LORD, mine horn is exalted in the LORD: my mouth is enlarged over mine enemies; because I rejoice in thy salvation. 2 There is none holy as the LORD: for there is none beside thee: neither is there any rock like our God. 3 Talk no more so exceeding proudly; let not arrogancy come out of your mouth: for the LORD is a God of knowledge, and by him actions are weighed. 4 The bows of the mighty men are broken, and they that stumbled are girded with strength. 5 They that were full have hired out themselves for bread; and they that were hungry ceased: so that the barren hath born seven; and she that hath many children is waxed feeble. 6 The LORD killeth, and maketh alive: he bringeth down to the grave, and bringeth up. 7 The LORD maketh poor, and maketh rich: he bringeth low, and lifteth up. 8 He raiseth up the poor out of the dust, and lifteth up the beggar from the dunghill, to set them among princes, and to make them inherit the throne of glory: for the pillars of the earth are the LORD's, and he hath set the world upon them. 9 He will keep the feet of his saints, and the wicked shall be silent in darkness; for by strength shall no man prevail. 10 The adversaries of the LORD shall be broken to pieces; out of heaven shall he thunder upon them: the LORD shall judge the ends of the earth; and he shall give strength unto his king, and exalt the horn of his anointed".
