Matthew 24: 28 Also, on the matter of clothing, why are YOU anxious? Take a lesson from the lilies of the field, how they are growing; they do not toil, nor do they spin; 29 but I say to YOU that not even Sol´o·mon in all his glory was arrayed as one of these. 30 If, now, God thus clothes the vegetation of the field, which is here today and tomorrow is thrown into the oven, will he not much rather clothe YOU, YOU with little faith? 31 So never be anxious and say, ‘What are we to eat?’ or, ‘What are we to drink?’ or, ‘What are we to put on?’ 32 For all these are the things the nations are eagerly pursuing. For YOUR heavenly Father knows YOU need all these things. 33 “Keep on, then, seeking first the kingdom and his righteousness, and all these [other] things will be added to YOU. 34 So, never be anxious about the next day, for the next day will have its own anxieties. Sufficient for each day is its own badness.
One of the easily understandable bible verses that tackles about the simplicity of life and the importance of putting the kingdom and its promises in our lives first.
