Reaping

Galatians 6:7-9 KJV

Be not deceived; God is not mocked: for whatsoever a man soweth, that shall he also reap. For he that soweth to his flesh shall of the flesh reap corruption; but he that soweth to the Spirit shall of the Spirit reap life everlasting. And let us not be weary in well doing: for in due season we shall reap, if we faint not.

This passage has nothing to do with forgiveness.  God will always forgive, but when we choose wrong, pleasing our flesh, it is our flesh, our earthly bodies, that will reap corruption.
Forgiveness is for the soul, or spirit. But reaping affects both flesh and spirit.
That grass might look greener till you've discovered the cesspool that resides there, feeding crap to the deceptively green lawn.

So, once you realize the cesspool you are in, and you are tired of the crap, what do you do? Pour gas on the cesspool and burn it? No, because usually that pool of crap is a person. Often it's the very person you swapped sides of the fence for. That person has a soul, and also needs to be reconciled with God. Destroying that person will also burn you, adding to your sorrow. So what, then?

Read verse nine, again. That's your answer.

"Do right, do right, till the stars fall, do right!" - Lee Roberson.

Be not weary, don't give up. When you have nothing to rejoice about, rejoice that your name is written in heaven, and just continue to do right. When the time is right, you will be amazed at what God does.

And let us not be weary in well doing: for in due season we shall reap, if we faint not.
