God Hears the Prayers of His People

Sometimes, it takes awhile. Because, G-d knows when it is best, or not good to have. You just have to be patient and wait. It can take years.

God is not slack on His gifts to those that pray for others ahead of themselves.

I definitely agree. God hears all our prayers that we pray for others and he hears prayers that others pray for individuals that they may not even know. He answers when it is appropriate at the right time and if he does not it does not mean that he has forgotten about us.
