Everybody is praying so that they can receive what they have been asking for from God and the only way that can be done or achieved is by praying in faith. 
We should not have any single doubts that God can do what we have been asking from him. Just pray unto Him and believe that he will grant your wishes onto you. 

Praying simply means asking from God what we cannot do by ourselves. When we ask God to do something for us, it means that we cannot achieve it all by ourselves and that is why we need to pray. 

Philippians 4:6 says; *Have no anxiety about anything, but in everything by prayer and supplication with thanksgiving let your requests be made known to God.*

This is written in the Bible and in the correct Bible at that. As we all know, anything and everything written in the correct Bible is from God. If God can tell us not to worry, we should not worry. All we have to do is pray unto him and believe that’s what we want is going to happen.

In our lives on earth, there are so many anxieties and we just have to be calm. It’s normal to be anxious but we should always have it in mind that if we can pray unto God, our problems will be over. 
God has told us to make what we want known to Him and we should do just that. 

God is usually happy when we come unto Him and tell Him our problems. That means we trust Him that He can do it. If you trust someone, believe in Him and never have any doubt. 

Hebrews 11:6 says; *But without faith it is impossible to please him: for he that cometh to God must believe that he is, and that he is a rewarder of them that diligently seek him.*

Just have faith and when you do so, the Lord will come for you in an amazing way!
