For every action there is an equal and opposite reaction. This is one of the primary laws of nature. This reaction can also be referred to as the consequences of the action. If you do such and such, thus and thus will be the result. Every time. This example applies not only to things of a physical nature, such as wind, explosives, et cetera, but also to things that we do in our daily lives. The very essence of life is the reaction of others and ourselves to the actions that we take. Although it doesn't always seem as though there are reactions to what we do, if you look closely, you will see that in fact there are.
He that leads into captivity shall go into captivity. He that kills with the sword must be killed with the sword. Here is the patience and the faith of the saints. (Revelation 13:10)
The same principle applies here. You will reap what you sow, regardless of what it may be. If you sow love, mercy, compassion, and righteousness, you will reap love, mercy, compassion, and righteousness. If you sow hatred, lust, greed, and envy, you will reap hatred, lust, greed, and envy. These are the consequences of your behavior.
If you doubt that you really are going to have to pay for your sins, or get reward for your righteousness, take a look at what transpired when the nation of Yisra'el disobeyed their Eloah and our Eloah, whose name is Yahuwah (yah-hoo-wah'), the Father of our Savior Yahushua. He promised Abraham some very good things if Abraham would obey Him and walk in His ways. Abraham did and he was called the friend of Yahuwah. He collected what Yahuwah had promised to him. Yahuwah also made promises about what would happen to those who did not obey His commandments and those who were disobedient got what He had promised them too. There are always consequences.
Yahuwah has destroyed individuals and entire nations because of their disobedience. He has likewise set up individuals and entire nations in splendor because they did obey. He has sent prophets to warn people and nations of what He was going to do to them if they failed to repent and return to Him. He wasn't kidding. He meant it. Those that did repent and return, He spared. Those who continued in their sinful ways, He destroyed. Just that simple, just that plain. Yahuwah does not make jokes. He is serious about His commandments and the fact that we must be in obedience to Him.
We aren't going to get any more prophets warning us until His two witnesses appear in Yeruwshalom. They are not going to be believed either. Until that time we have His written word to guide us and it contains all of the information required to follow His commandments. It also tells us the consequences if we don't. He is serious. We had better get that way. The time is short. Are you going to continue to serve Satan? Or are you going to turn about and serve the living Eloah? The choice is yours.
For those who return and obey, eternal life in paradise is the reward. To those who do not obey, the lake of fire awaits.
