The reason it's important

If the objective of our life was primarily to avoid sin, it wouldn't much matter whether we did it by grace or by brute force of will. (Let us set aside for a moment the impossibility of the latter.)

But it isn't!

So the reason it's important to turn to God when we're feeling weak and vulnerable isn't just to be helped through whatever degree of crisis we might be facing, and the reason for turning to Him when we are feeling strong isn't so that we won't stumble when we're feeling weak.

It's a little like the incredulous question the late Fr. Neuhaus raises in Death on a Friday Afternoon, while he's speculating about whether God's desire for every beloved son and daughter of His to be saved might actually be fulfilled. He talks about those whose response to that possibility is worry about the benefit of walking with the Lord, then, if our destiny ends up being the same, if God's grace really manages to overcome every person's sin. I'm probably paraphrasing his response: What's the point‽ The point is that you get to walk with the Lord!!

No benefit we might think passes us by when we turn away from sin to walk more closely with Him comes anywhere near that of knowing the One who loves us like no other! And no righteous side effect of avoiding sin compares with this joy, either.

There are many who approach faith as if it is primarily about its beneficial effects on society. They are as wrong as those who elevate any other gift of God above the presence of God Himself. The second greatest commandment is important, but there's a Reason it isn't the greatest!
