Have you ever trusted a person so much,who had the ability or resources to do something for you but never did it? Have you been in a situation where you thought that all you need will be met by some particular persons because they are your close friends or relations? Sometimes we even go to God in prayers while thinking that God will answer us using those persons. Just because He used your uncle the last time doesn't mean He will use him again. He may use your uncle to start a business for you, but He can also use a friend or other means to substain the business. He may use your aunty to start paying your school fees and He can use someone else to continue paying the fees for you.
We rely so much on one way that God must answer. We set our hearts always on a particular method through which God must answer, but God has A MILLION WAYS to meet your needs. Have you ever wondered why trees do not have one branch'. Trees always have several branches so that the farmer will always have fruits. The branch that bears more fruits this year may bear less or may even be cut off before the following season. The other branches will continue to bear fruit for the farmer. God made it like that.
In the same way, God has many 'branches' or ways to answer you.
Even if the brother says he can't marry you, God has more than A MILLION WAYS to bring you the best suitor. Don't look at the calendar (time), look at the commander (God).
Stop limiting Him by believing only. Your true position in prayer should not be who God is going to use. Your true position is to believe. Mark 9: 23 says "all things are possible to him that believes". Remember God has A MILLION WAYS.
