I know that our Father in Heaven can meet our needs, but we need to ask him to help us. Be specific with those things you are in need of as you pray. If God already knows what we need, why should we ask him? By asking him we are showing that we realize our dependence on him to meet our needs. Our Father in Heaven can answer our prayers and fulfill our needs, but we need to do our part both in action and through prayer.
In Mormon 9:27, we read: "O then despise not, and wonder not, but hearken unto the words of the Lord, and ask the Father in the name of Jesus for what things soever ye shall stand in need. Doubt not, but be believing, and begin as in times of old, and come unto the Lord with all your heart, and work out your own salvation with fear and trembling before him."
I received a letter from one of my past students who was serving his mission in Italy. As he left he assured me that he would be teaching all of the country of Italy as well as the Pope! I informed him that they have this thing for Catholicism over in Italy. Halfway through his mission he told me that things were going great and that they were teaching a lot of first discussions but not many second discussions.
He had been taught by his mission president that it was important for the missionaries to ask the Lord specifically for what they needed. This missionary then said, "I decided to start asking for the opportunity to teach the second discussion. In the next two days we found two families who have given us an appointment for the second discussion, as well as another lady. The Lord answered my prayers so fast. It's great!"
