"Behold the fowls of the air" - their main aim is to obey the principle of life that is in them and God looks after them. Jesus says that if you are rightly related to Him and obey His Spirit that is in you, God will look after your 'feathers.'
"Consider the lilies of the field" - they grow where they are put. Many of us refuse to grow where we are put, consequently we take root nowhere. Jesus says that if we obey the life God has given us, He will look after all the other things. Has Jesus Christ told us a lie? If we are not experiencing the "much more," it is because we are not obeying the life God has given us, we are taken up with confusing considerations. How much time have we taken up worrying God with questions when we should have been absolutely free to concentrate on His work? Consecration means the continual separating of myself to one particular thing. We cannot consecrate once and for all. Am I continually separating myself to consider God every day of my life?
"If God so clothe the grass of the field....shall He not much more clothe you?"
