Matthew 6:22
"The eye is the lamp of the body. So, if your eye is healthy, your whole body will be full of light,
your eye is healthy
The word here translated "healthy" (ἁπλοῦς) is typically rendered "sincere" or "generous".
At its base, the word conveys a singleness of mind, open, and unqualified.
- We take it to mean "sincere" when we consider simple, plain, or straightforward speech or conduct.
- On the other hand, we take it to mean "generous" when we consider open-hearted giving with no strings attached.
It may not at first be obvious how sincerity is related to generosity. The instructions for observing the Lord's release in Deuteronomy 15 illustrate the relationship so we can see it clearly.
Deuteronomy 15:1–2
At the end of every seven years you shall grant a release. And this is the manner of the release: every creditor shall release what he has lent to his neighbor. He shall not exact it of his neighbor, his brother, because the LORD's release has been proclaimed….
Deuteronomy 15:4–5
There will be no poor among you; for the LORD will bless you in the land that the LORD your God is giving you for an inheritance to possess— if only you will strictly obey the voice of the LORD your God, being careful to do all this commandment that I command you today.….
Deuteronomy 15:7–11
If among you, one of your brothers should become poor, in any of your towns within your land that the LORD your God is giving you, you shall not harden your heart or shut your hand against your poor brother, but you shall open your hand to him and lend him sufficient for his need, whatever it may be. Take care lest there be an unworthy thought in your heart and you say, "The seventh year, the year of release is near," and your eye look grudgingly on your poor brother, and you give him nothing, and he cry to the LORD against you, and you be guilty of sin. You shall give to him freely, and your heart shall not be grudging when you give to him, because for this the LORD your God will bless you in all your work and in all that you undertake. For there will never cease to be poor in the land. Therefore I command you, "You shall open wide your hand to your brother, to the needy and to the poor, in your land."
Sincerity and integrity are tied to generosity in Psalm 112, as well.
Psalm 112:1, 4–5
Praise the LORD!
Blessed is the man who fears the LORD,
who greatly delights in his commandments…!
Light dawns in the darkness for the upright;
he is gracious, merciful, and righteous.
It is well with the man who deals generously and lends;
who conducts his affairs with justice.
Finally, the immediate context of our current reading in Matthew also suggests that we focus more on the "generosity" aspect of this word. The passage right before this one ended by saying, "Where your treasure is, there your heart will be also" (Matthew 6:21). The next passage in our study says simply, "You cannot serve God and money" (Matthew 6:24). With our current reading sandwiched between passages that clearly address our attitude toward money, we feel confident that the intended meaning here in verse 22 is for us to prove "generous".
