Matthew 6:25 begins with some great tips for living in the now.
Take no thought for your life, what ye shall eat, or what ye shall drink; nor yet for your body, what ye shall put on. Is not the life more than meat, and the body than raiment? Behold, the fowls of the air: for they sow not, neither do they reap, nor gather into barns; yet your heavenly Father feedeth them. Are ye not much better than they? Skip down to verse 34 Take therefore no thought for the morrow: for the morrow shall take thought for the things of itself. Sufficient unto the day is the evil thereof.
So I guess I am saying we need to let our heavenly Father take care of us. Sure we need to do the things necessary to provide for ourself but he does not want us to worry. The birds of the field trust in food for the day so should we.
