There is no failure in a Christian's life, rather you only see a failing prayer because most Christians misunderstood this process, prayer shouldn't be procrastinated nor done in the fleshly form. If you can pray, your future got no worries because men of prayer are men of authority. When we pray in the spirit, we should picture the answer in our heart with full expectation.

When you are a man that pray in the spirit, you get it the perfect way you desire it.
