Hannah had been thought to be drunk, but after she told Eli, the priest that she wasn't but was earnestly praying for a son, he accepted this and blessed her, praying that her prayers would be answered. Hannah was now at rest that the Lord had heard her prayers. This is how we must be, after having asked for the Lord's help, answering our needs, we can rest knowing that he will have heard us and will answer our prayers in due course. In Hannah's situation her prayers were asked after a while and she gave birth to Samuel. Like her, sooner or later out prayers will be answered and we will rejoice and give thanks to the Lord for this.
