Mark 11:24

For this reason I am telling you, whatever things your ask for I prayer (in accordance with God’s will), believe (with confident trust) that you have received them, and they will be given to you.

Prayer is the communication of our needs to God. God is our protector and provider for all our needs, and when we pray, we call on God to send those provisions to us. Our faith in God is assured by His word that our prayers will be answered. When we believe we can receive from God and have our prayers answered.
