We are His reliant, as God's children. "As a father, the father pityed his children, so the Lord compassionately compassionated those who fear Him," says the Bible. You believe and are entitled to anything from your parents. Because God is responsible for our good, it's told us to take care of Him because He cares about us.
Behold, what manner of love the Father hath bestowed upon us, that we should be called the [children] of God . . .
—1 John 3:1
Since we are relying on God, Jesus said, "Don't let your heart be troubled." God said: "I'll take care of the burden — don't worry about it, don't leave it to me." If they didn't display their needs audaciously they wouldn't be natural. God is conscious that for the necessities of life we are relying on Him. This is why he said, "Pray and be granted to you, search and find, knock and it shall be opened to you." For this reason, he said.
