Let us look at a familiar illustration used by our Master of God's minute care for those who fully trust and follow Him. One able man has called what I am referring to 'the doctrine of the odd sparrow'. Matthew records how, on one occasion, Jesus said, 'Are not two sparrows sold for a farthing? and one of them shall not fall to the ground without your Father'. But, turning to Luke, we find a slight variation in what Jesus said, 'Are not five sparrows sold for two farthings, and not one of them is forgotten before God'. Now, do you see the point of Luke's putting of it? It is as if the dealer had said to the buyer, 'Look here, you want a farthing's worth of sparrows. Well, you can have two; but, if you will buy two farthingsworth, I will _throw the odd one in for nothing_'. Two for a farthing; five for a halfpenny. But see; of that odd sparrow thrown in as hardly worth counting, Jesus said, 'Not one of them is forgotten before God. Not one shall fall to the ground without your Father. Are ye not of more value than many sparrows?' Now, in the light of that illustration, turn once more to the Apostolic message, 'Be careful for nothing', and I think you will find good reason for believing the promise, 'The peace of God shall keep your hearts through Jesus Christ'. Before leaving this matter of worry, I suggest that we look well to find the cause of the trouble; for, alas! it is not unfrequently the case that care or undue anxiety arises from positive sin in the heart. Some of you worry in respect of your position in life as compared with other people's; but are you sure that some of this fratch and distress does not arise from feelings of envy, or jealousy, or discontent? Others may worry because of comparative poverty, but is it not often pride or ambition concerning yourselves or your children, and a desire to be level with your neighbours, which causes the trouble? You worry, perhaps, because people cross your purposes and upset your plans and irritate you needlessly; but is not the secret really that you resent interference, and want to have your own way? Now, before blaming your circumstances, I suggest you have a thorough self-examination, for it may be that the inward trouble is due to unbelief, selfishness, ambition, pride, or some other form of heart sin, and that evil must be dealt with before perfect peace can prevail. May I come very close to you, and ask, Is it not true of some that, far from being kept by the peace of God which passeth all understanding, you are in a condition, an attitude of mind, which distinctly hinders the enjoyment of such a blessing? Some, I fear, have not got even as far as saying, 'Being justified by faith, I have peace with God'. There is some sin, some indulgence, which God is against; and as rebellion and peace are opposed to each other, you cannot have guidance and peace and spiritual blessings until you cast yourselves at the mercy-seat, and take Christ as your Saviour.
