Imagine you are God. There are 2 persons praying at the same time. You pray that in front of your house, that house that is being built will not be built so that it will not block your window view. Another person prays that his house in front of your window view will be built, so that he will be able to live in it. If you are God, which prayer will you make it comes true. Of course, the prayer that the house to be built so that people can live in. Therefore, when your prayers reach God, He may not make them come true because of some Divine reasons. Trust God to be a fair & just God.
Me & wife discover if you kneel down during prayer, it is more effective. The Prayers to Jesus Christ come true more effectively.
