They have not known nor understood: for he hath shut their eyes, that they cannot see; and their hearts, that they cannot understand. And none considereth in his heart, neither is there knowledge nor understanding to say, I have burned part of it in the fire; yea, also I have baked bread upon the coals thereof; I have roasted flesh, and eaten it: and shall I make the residue thereof an abomination? shall I fall down to the stock of a tree? He feedeth on ashes: a deceived heart hath turned him aside, that he cannot deliver his soul, nor say, Is there not a lie in my right hand?
~ Isaiah 44:18-20
For ye were sometimes darkness, but now are ye light in the Lord: walk as children of light:
~ Ephesians 5:8
Jesus said unto him, If thou wilt be perfect, go and sell that thou hast, and give to the poor, and thou shalt have treasure in heaven: and come and follow me.
~ Matthew 19:21
Let your conversation be without covetousness; and be content with such things as ye have: for he hath said, I will never leave thee, nor forsake thee.
~ Hebrews 13:5
If ye were of the world, the world would love his own: but because ye are not of the world, but I have chosen you out of the world, therefore the world hateth you.
~ John 15:19
Expository Thoughts on the Matthew’s Gospel, 6:16-24, by J.C. Ryle.
Moreover when you fast, don’t be like the hypocrites, with sad faces. For they disfigure their faces, that they may be seen by men to be fasting. Most certainly I tell you, they have received their reward. But you, when you fast, anoint your head, and wash your face; so that you are not seen by men to be fasting, but by your Father who is in secret, and your Father, who sees in secret, will reward you.”Don’t lay up treasures for yourselves on the earth, where moth and rust consume, and where thieves break through and steal; but lay up for yourselves treasures in heaven, where neither moth nor rust consume, and where thieves don’t break through and steal; for where your treasure is, there your heart will be also.
“The lamp of the body is the eye. If therefore your eye is sound, your whole body will be full of light. But if your eye is evil, your whole body will be full of darkness. If therefore the light that is in you is darkness, how great is the darkness!
“No one can serve two masters, for either he will hate the one and love the other; or else he will be devoted to one and despise the other. You can’t serve both God and Mammon.”
There are three subjects brought before us in this part of our Lord’s sermon on the mount. These three are fasting, worldliness, and singleness of purpose in religion.
Fasting, or occasional abstinence from food, in order to bring the body into subjection to the spirit, is a practice frequently mentioned in the Bible, and generally in connection with prayer. David fasted, when his child was sick. Daniel fasted, when he sought special light from God. Paul and Barnabas fasted, when they appointed elders. Esther fasted, before going in to Ahasuerus. It is a subject about which we find no direct command it the New Testament. It seems to be left to every one’s discretion, whether he will fast or not. There is great wisdom in this. Many a poor man never has enough to eat, and it would be an insult to tell him to fast. Many a sickly person can hardly be kept well with the closest attention to diet, and could not fast without bringing on illness. It is a matter in which every one must be persuaded in his own mind, and not be hasty to condemn others, who do not agree with him. One thing only must never be forgotten. Those who fast should do it quietly, secretly, and without ostentation. Let them not “appear to men” to fast. Let them not fast to man, but to God.
Worldliness is one of the greatest dangers that beset man’s soul. It is no wonder that we find our Lord speaking strongly about it. It is an treacherous, harmful, enticing, and powerful enemy. It seems so innocent to pay close attention to our business! It seems so harmless to seek our happiness in this world, so long as we keep clear of open sins! Yet here is a rock on which many make shipwreck to all eternity. They “lay up treasure on earth,” and forget to “lay up treasure in heaven.” May we all remember this! Where are our hearts? What do we love best? Are our chief affections on things in earth, or things in heaven? Life or death depends on the answer we can give to these questions. If our treasure is earthly, our hearts will be earthly also. “Where your treasure is, there will your heart be.”
Singleness of purpose is one great secret of spiritual prosperity. If our eyes do not see distinctly, we cannot walk without stumbling and falling. If we attempt to work for two different masters, we are sure to give satisfaction to neither. It is just the same with respect to our souls. We cannot serve Christ and the world at the same time. It is vain to attempt it. The thing cannot be done. The ark and Dagon will never stand together. God must be king over our hearts. His law, His will, His precepts must receive our first attention. Then, and not until then, everything in our inward man will fall into its right place. Unless our hearts are so ordered, everything will be in confusion. “Your whole body will be full of darkness.”
Let us learn from our Lord’s instruction about fasting, the great importance of cheerfulness in our religion. Those words, “anoint your head, and wash your face,” are full of deep meaning. They should teach us to aim at letting men see, that we find Christianity makes us happy. Never let us forget that there is no religion in looking melancholy and gloomy. Are we dissatisfied with Christ’s wages, and Christ’s service? Surely not! Then let us not look as if we were.
Let us learn from our Lord’s caution about worldliness what immense need we all have to watch and pray against an earthly spirit. What are the vast majority of professing Christians round us doing? They are “laying up treasure on earth.” There can be no mistake about it. Their tastes, their ways, their habits tell a fearful tale. They are not “laying up treasure in heaven.” Oh! let us all beware that we do not sink into hell by paying excessive attention to lawful things. Open transgression of God’s law slays its thousands, but worldliness its tens of thousands.
Let us learn from our Lord’s words about the “single eye,” the true secret of the failures, which so many Christians seem to make in their religion. There are failures in all quarters. There are thousands in our churches uncomfortable, ill at ease, and dissatisfied with themselves, and they hardly know why. The reason is revealed here. They are trying to keep in with both sides. They are endeavoring to please God and please man, to serve Christ and serve the world at the same time. Let us not commit this mistake. Let us be decided, thorough-going, uncompromising followers of Christ. Let out motto be that of Paul, “One thing I do.” (Phil. 3:13.) Then we shall be happy Christians. We shall feel the sun shining on our faces. Heart, head, and conscience will all be full of light.
