I believe Matt 6:33 is Jesus telling us that if we seek Him we need not worry and that He will continue to take care of our basis needs in life. The blessings are the things we need in this life as he has mentioned concerning food and clothing for our physical bodies.
I hope we as believers don't spread the idea that if we follow God that we will receive all kind of physical or material blessings. I have heard some refer to that type of belief as "name it and claim it" theology.
My belief is God prefers us to be happy with the essentials we need to live a happy and joyful like in Christ, because our true blessings will be realized in eternity with Him.
