Paul is a classic example for us. He, as Saul, sowed murder against the believers and got grace instead of death from the Lord.
Almost always it seems to me "what one sows is what one reaps" is taken out of context. Here is the context of that saying:
Gal 6:6-10 Now let him who is being instructed in the word
be contributing to him who is instructing, in all good things." (7)
Be not decived, God is not to be sneered at, for whatsoever a man may be sowing, this shall he be reaping also, (8) for he who is sowing for his own flesh, from the flesh shall be reaping corruption, yet he who is sowing for the spirit, from the spirit shall be reaping life eonian." (9) Now we may not be despondent in ideal doing, for in due season we shall be reaping, if we do not faint." (10) Consequently, then, as we have occasion, we are working for the good of all, yet specially for the family of faith."
Good sowing and reaping:
- Sowing = contributing to the one instructing you = sowing for the spirit.
- Reaping = from the spirit reaping life eonian. This is the enjoying of the realization of the life pertaining to the future eons NOW.
Doing good now will allow us to reap in the future if we do not faint, i.e., don't give up.
Bad sowing and reaping:
- Sow = for one's own flesh
- Reap = reap corruption from the flesh
This reaping of corruption from the flesh may be automatic?
