Mark 9:23
Jesus said to him, (You say to Me,) If You can? “All things are possible for the one who believes and trusts (in Me)!”

It doesn’t take immense faith (think mustard seed). It doesn’t take hours of praying, begging God to hear the prayer. It takes belief that is unshakable in God. When we have the sold-out, totally convinced kind of faith with no doubts about what we believe and who we believe in! Then God will hear our prayer and make sure we receive our victory.
