Wherefore it came to pass, when the time was come about after Hannah had conceived, that she bare a son, and called his name Samuel, saying, Because I have asked him of the Lord. 1 Samuel 1:20
If you have ever read the story of Hannah, then you will understand that delayed does not mean denied. If you haven't read the story, I suggest you do so (see 1Samuel 1:1-28).
The story starts out with stating how Hannah was one of two wives of Elkanah. Peninnah, the other wife, had children; Hannah did not. Because Hannah was unable to have children, Peninnah would make fun of her, making Hannah very unhappy. She provoked her so much, for so long, that Hannah wept and stopped eating. Nevertheless, Hannah prayed to the Lord and vowed a vow, "O LORD of hosts, if thou wilt indeed look on the affliction of thine handmaid, and remember me, and not forget thine handmaid, but wilt give unto thine handmaid a man child, then I will give him unto the LORD all the days of his life, and there shall no razor come upon his head." Now you have to be very careful about making vows to God. Make sure that whatever vow you make, you are prepared to keep it!
One thing I have learned from reading this story is that when we come into the presence of the Lord, we need to go to Him with expectancy in our hearts. We need to know that our petition will be heard and that God will answer us.
What a wonderful relationship Hannah must have had with God to not only petition Him, but also to make a vow to Him. You just don't make a vow to anyone. There has to be a relationship.
I'm sure that wasn't the first time Hannah had prayed to God for a child. Her desire to have a man child was stronger than her desire to give up. She knew that God was the only one who could give her a man child, and that because it hadn't happen, didn't mean that it wouldn't happen.
We need to remember that just because we haven't been blessed with what we asked God for, doesn't mean we won't receive it. It's all about God's timing. After all, He knows what best for us. REMEMBER: DELAYED DOES NOT MEAN DENIED.
And she said, Oh my lord, as thy soul liveth, my lord, I am the woman that stood by thee here, praying unto the LORD. For this child I prayed; and the LORD hath given me my petition which I asked of him: Therefore also I have lent him to the LORD; as long as he liveth he shall be lent to the LORD. And he worshipped the LORD there. 1Samuel 1:26-28
