Luke 12:22 And he said unto his disciples, Therefore I say unto you, Take no thought for your life, what ye shall eat; neither for the body, what ye shall put on.
Luke 12:23 The life is more than meat, and the body is more than raiment.
Life is more than existing. Most have food and clothing so this is not to be our concern. Life should have more meaning than this.
Luke 12:24 Consider the ravens: for they neither sow nor reap; which neither have storehouse nor barn; and God feedeth them: how much more are ye better than the fowls?
Ravens are fed by God, they do not build barns; perhaps referring to the man in the parable, who had planned to build a bigger barn to store all of his increase in food. This man's soul would be taken, so what use was all of his planning? A raven is fed and God can even use ravens to feed another, as with Elijah in time of need.
1 Ki 17:4 And it shall be, that thou shalt drink of the brook; and I have commanded the ravens to feed thee there.
1 Ki 17:5 So he went and did according unto the word of the LORD: for he went and dwelt by the brook Cherith, that is before Jordan.
1 Ki 17:6 And the ravens brought him bread and flesh in the morning, and bread and flesh in the evening; and he drank of the brook.
God provides for his servants.
Luke 12:25 And which of you with taking thought can add to his stature one cubit?
All of our thoughts and concerns, cannot change our physical stature. Many spend much time trying to change the way they look, to be more accepted by the world. Few are satisfied with how they look. What about character and moral values? How much time do we spend in God's word and doing his will to please him? How many are satisfied with their spiritual life? How many give this no thought at all, until their soul is required?
Luke 12:26 If ye then be not able to do that thing which is least, why take ye thought for the rest?
Forget the worldly concerns and put your focus on the things of God. This does not mean that we are to cease from working. We have worldly responsibilities so that we may bless others in this world.
1 Tim 5:5 Now she that is a widow indeed, and desolate, trusteth in God, and continueth in supplications and prayers night and day.
1 Tim 5:6 But she that liveth in pleasure is dead while she liveth.
1 Tim 5:7 And these things give in charge, that they may be blameless.
1 Tim 5:8 But if any provide not for his own, and specially for those of his own house, he hath denied the faith, and is worse than an infidel. We have physical responsibilities and we have responsibilities that are spiritual. Often they are close together. Sometimes they are distinctly different.
Mat 22:17 Tell us therefore, What thinkest thou? Is it lawful to give tribute unto Caesar, or not?
Mat 22:18 But Jesus perceived their wickedness, and said, Why tempt ye me, ye hypocrites?
Mat 22:19 Show me the tribute money. And they brought unto him a penny.
Mat 22:20 And he saith unto them, Whose is this image and superscription?
Mat 22:21 They say unto him, Caesar's. Then saith he unto them, Render therefore unto Caesar the things which are Caesar's; and unto God the things that are God's.
We must be responsible in all of our affairs, for God is faithful to us.
