Jesus told his disciples:
“Have faith in God. If you have faith in God and don’t doubt, you can tell this mountain to get up and jump into the sea, and it will.
Everything you ask for in prayer will be yours, if you only have faith.
Whenever you stand up to pray, you must forgive what others have done to you. Then your Father in heaven will forgive your sins.”

This is rather hard to believe. Who thinks they can pray for a mountain to jump into the sea and it will. The key here is to have faith and believe that God will grant you what you ask. Of course, if you ask God to make you a millionaire tomorrow, that may not happen. If you read about some of the miracles Jesus performed when he walked the earth, the people he healed all had faith in him and believed that he could heal them. He always said to them “your faith has made you well”. That is the type of faith Jesus is speaking about to his disciples in this bible verse.
