The Law of Sowing and Reaping - The Flip Side

The scripture for this post:

Then David said to Nathan, "I have sinned against the LORD." Nathan replied, "The LORD has taken away your sin. You are not going to die. But because by doing this you have made the enemies of the LORD show utter contempt, the son born to you will die."

2 Samuel 12:13-14

Do not be deceived: God cannot be mocked. A man reaps what he sows. The one who sows to please his sinful nature, from that nature will reap destruction; the one who sows to please the Spirit, from the Spirit will reap eternal life.

Galatians 6:7-8

There is a wonderful lesson in http://www.gracevalley.org/sermon_trans/2000/Law_of_Sowing_and_Reaping.html

It explains with clarity the long line of consequences of reaping destruction from sin. The example used is the sin of David with Bathsheba. From that lesson I quote:

"Our Actions Matter

You have probably heard the slogan, "Once saved, always saved." The idea behind it is that it doesn’t matter what Christians do; they will be saved because they invited Jesus into their hearts. Those who use this slogan will quote Paul’s words in Romans 5:20, "Where sin increased, grace increased all the more," but what they are really saying is, "Let us go on sinning that grace may abound." They will say, "I believe in eternal security" and then they sin without fear of any consequences.

I want to tell you that such notions are delusionary. Not only are such people ignoring Paul’s declaration in Romans 6:1, "What shall we say, then? Shall we go on sinning so that grace may increase? By no means!" but they are also ignoring his words to the Galatians, "You, my brothers, were called to be free. But do not use your freedom to indulge the sinful nature. . ." (Galatians 5:13). In Galatians 6:7 Paul instructed, "Do not be deceived: God cannot be mocked. A man reaps what he sows." We cannot sow weeds and reap wheat, nor can we sow thorns and reap strawberries. Hosea tells us if we sow wind, we will reap a whirlwind, and if we sow to sin, we will reap destruction, not righteousness. That is why "Once saved, always saved"—this claim to justification without clear evidence of sanctification—is nothing but equivocation and sheer prevarication."
