We all need faith to please God. Jesus said "If you have faith the size of a mustard seed, you will say to this mountain "Move and it will move", Now even though Jesus did not mean literal mountains, He is talking about the mountains in our daily lives.
We all have issues or problems that arise in our lives and we want God to get rid of them for us but the problem most of the time is "doubt". Either we doubt God can do it or we listen to others instead of what God says to us in His word. So what can you do to elevate your faith enough to move mountains?
First, you must start small by believing in God for the small things. If you prayed and God answered it, thank Him for it because that reassures your faith in Him.
Secondly, be aware of how you talk to yourself, watch what comes out of your mouth. make sure what you speak lines up with God's word.
Lastly, be willing to go the extra mile which means, if you need to pray more do so. If you need to fast, do so. Because sometimes, it takes a lot to break some things off of you. When you start aligning yourself with God, you will see mountains start to move in your life.
