Some people see miracles and others don't. It's not fate or luck. There are principles we have to follow to see His power manifest. 

You might be in a situation right now where you are facing an absolute disaster financially, physically, emotionally, or in your relationships. Maybe nothing seems to be working. When we are in the midst of the storm, there are two possible situations: either we are like Jonah (Johan 1-3) who ran from God and got into trouble due to his rebellion, or we are like Peter (Matthew 14:22-29) who followed the will of Jesus when the storm hit. You need a word from God. You need a inner witness from the Holy Spirit that what you are doing is what God told you to do.

When problem comes, you might feel condemned and think, "I brought this on myself. I deserve it." If you are there because of your own rebellion and disobedience to God, then you should repent, like Jonah did in the belly of the fish. God loves you and will set you free.  However, if you are doing what God told you to do, like Peter following Jesus on the sea, you need to stop doing anything according to your natural ability and only depend on God, trusting that God would keep you from sinking. That's how Peter was able to walk on the water. 

God intends for mankind to live in Him and through Him. A normal Christian life is for you to be drawing upon God's ability and power.
