There are possibly good reasons for it; but, of course, there may not be.
For choosing the green one over the blue—or the other way around.
“Do there have to be good reasons?”
No, of course not—basically, the choice of a color is a matter of indifference, a matter of preference, all other things being equal. There are no biblical reasons for one option over the other if it doesn’t involve stewardship of the Lord’s money or something else like that. Then something additional is at stake.
“Is every choice one in which one either chooses for Christ or against Him?”
In one sense “yes”; in another “no.”
All choices are for or against Christ in the sense that we must do all we do for His honor and in order to serve Him. So the basic choice of blue or green is not necessarily indifferent. Christians should choose—whatever we choose—because we are interested in glorifying Him by the choice. So, a color, of course, might be a major issue if other factors are involved that affect whether or not He will be honored by it.
Well, let’s see . . . If the choice were determined because we wanted to “show off” by being different from others, there might be a matter of pride mixed in with our choice. Or, better still, if the choice of one color over the other meant that we were in rebellion against what was ordered or expected in a given situation, that choice might become an issue. The point is that, under those conditions, we make it an issue when there is no need to do so.
“I’m still not clear.”
OK. I’ll try again. Suppose the green one is a Mercedes and the blue one is a Ford. Then, an additional factor of the money involved might (in various situations) bring in a consideration of Romans 13:8, “Don’t owe anybody anything . . ..” Paul was talking about taxes and other financial transactions (vv. 6,7). You see . . .
“Does that mean I can’t buy a house or a car unless I have the cash to pay for it?”
It would be desirable if you could put up the cash but, of course, with such large purchases most of us can’t. We have to take out a loan or mortgage. The point of the passage is whether or not you will be able to pay off the loan in the allotted amount of time agreed upon in the contract. If you have no reasonably good expectation of paying for the Mercedes, then you’d better choose the Ford. But when you do, whether it is green or blue won’t make any difference. The choice of the color is indifferent.
If, however, it comes down to a blue Mercedes over against a green Ford on the used car lot, and you want the blue car—but have no expectation of paying off the loan in a timely manner—the choice based on color becomes an issue. So, the preference becomes a secondary matter, while obeying Romans 13:8 is not.
“I get It; if I want the blue under those circumstances, I can’t get it.”
You got it!
