Biblical faith is a powerful weapon. Mountains yield to its power. Sin, Satan, and sorrow must bow before its authority. Faith is among the greatest of God's gifts to His children.
Faith has the remarkable ability to enable us to hold in our hands things that have yet to be seen, to hold in our hearts things that have yet to appear.
Answers to prayer come when we pray according to the will of God.
1 John 5:14-15 And this is the confidence that we have in him, that, if we ask any thing according to his will, he heareth us: And if we know that he hears us, whatsoever we ask, we know that we have the petitions that we desired of him.
When we pray "in Jesus' name" we are praying for His purpose and will to be fulfilled. Selfish prayers will not be answered.
God can strengthen your faith if you ask.
Mark 11:22 And Jesus answering saith unto them, Have faith in God.
