God does say He will provide all of our needs. Are we not more important than the flowers that God provides water and sun for? Are we not more important than the birds that God feeds?
Matthew 7:11 (King James Version)
11If ye then, being evil, know how to give good gifts unto your children, how much more shall your Father which is in heaven give good things to them that ask him?
Matthew 21:21-23 (King James Version)
21 Jesus answered and said unto them, Verily I say unto you, If ye have faith, and doubt not, ye shall not only do this which is done to the fig tree, but also if ye shall say unto this mountain, Be thou removed, and be thou cast into the sea; it shall be done.
22And all things, whatsoever ye shall ask in prayer, believing, ye shall receive.
John 16:23-25 (King James Version)
23And in that day ye shall ask me nothing. Verily, verily, I say unto you, Whatsoever ye shall ask the Father in my name, he will give it you.
24Hitherto have ye asked nothing in my name: ask, and ye shall receive, that your joy may be full. 25These things have I spoken unto you in proverbs: but the time cometh, when I shall no more speak unto you in proverbs, but I shall shew you plainly of the Father
James 4:2-4 (King James Version)

3Ye ask, and receive not, because ye ask amiss, that ye may consume it upon your lusts. 4Ye adulterers and adulteresses, know ye not that the friendship of the world is enmity with God? whosoever therefore will be a friend of the world is the enemy of God.
Hebrews 11:6 (King James Version)
6But 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.
2 Timothy 1:7 (King James Version)
7For God hath not given us the spirit of fear; but of power, and of love, and of a sound mind.
1 Peter 5:7-9 (King James Version)
7Casting all your care upon him; for he careth for you.
8Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour: 9Whom resist stedfast in the faith, knowing that the same afflictions are accomplished in your brethren that are in the world.
Philippians 4
4Rejoice in the Lord always: and again I say, Rejoice.
5Let your moderation be known unto all men. The Lord is at hand.
6Be careful for nothing; but in every thing by prayer and supplication with thanksgiving let your requests be made known unto God.
7And the peace of God, which passeth all understanding, shall keep your hearts and minds through Christ Jesus. 8Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these things.
1 John 4:17-19 (King James Version)
17Herein is our love made perfect, that we may have boldness in the day of judgment: because as he is, so are we in this world.
18There is no fear in love; but perfect love casteth out fear: because fear hath torment. He that feareth is not made perfect in love. 19We love him, because he first loved us.
