All sorts of people attend church. Some you like; some you don’t. A few rub us wrong. Fewer still seem to have it in for us. What are we to do? Avoidance comes to mind. But what’s God’s standard?
We love because he first loved us. If anyone says, “I love God,” and hates his brother, he is a liar; for he who does not love his brother whom he has seen cannot [or, how can he] love God whom he has not seen. And this commandment we have from him: whoever loves God must also love his brother. 1 John 4:19-21 English Standard Version (ESV)
Okay, so if we don’t love our brother then we don’t love God? The word used for love, here, is ἀγαπάω (agapaō), or sacrificial love. Though affection may arise from this kind of love, the essence of agape toward our brother or sister is: unconditional, generous effort for another’s welfare. For deeper insight concerning these verses, consider what Calvin says:
We love him …This love [of God] cannot exist, except it generates love [toward our brothers and sisters]. Hence [the Apostle John] says, that they are liars who boast that they love God, when they hate their brethren.
…The Apostle takes [for] granted what ought…to appear evident to us, that God offers himself to us in those men who bear his image, and that he requires the duties, which he does not want himself, to be performed to them, according to Psalm 16:[2-3], where we read,
“My goodness reaches not to thee, O Lord;
towards the saints who are on the earth is my love.”
…John…shows how fallacious is the boast of everyone who says that he loves God [who is invisible], and yet loves not God’s image which is before his eyes.
And this commandment …He not only gave a commandment respecting the love of God, but [commanded] us also to love our brethren. We must therefore so begin with God, as that there may be at the same time a transition made to men.
Echoing John, the Apostle Paul, in the twelfth chapter of the Letter to the Romans, says in part:
Live in harmony with one another. Do not be haughty, but associate with the lowly. Never be wise in your own sight. Repay no one evil for evil, but give thought to do what is honorable in the sight of all. If possible, so far as it depends on you, live peaceably with all. Romans 12:16-18 ESV
Further, we look to other ‘one anothers’ in scripture. Almost all of these are commands for us to act upon for our brethren’s welfare.
So, let us exert unconditional, generous effort for our brother’s or sister’s welfare by praying for their needs, forgiving and asking forgiveness, and supplying material kindnesses to them. Who knows, perhaps affection may arise afterward.
