Dear Heavenly Father thank you for another day, for a successful day, be praised forever.
Cleanse us Father of all our filth through the blood of Jesus, make us receptive to your word, make us fertile ground, let your word germinate and bear fruit in multiple fold in our lives. Amen. Glorify your name, we decrease that you increase, for your strength is made perfect in our weakness. Let your will be done. Amen.

Ephesians 6:8
[8]knowing that whatever good anyone does, he will receive the same from the Lord, whether he is a slave or free.

Let me start by saying that 'good' is relative, based on the time and circumstances.
The word of God says that whatever good anyone does. Note the words whatever and anyone, implying that even if the doer of this good deed had been doing bad all his life prior, God will still reward that good deed. It's amazing.
Another thing I will like to clarify here is even though You are assured of the reward, you can't be assured of the time and that is one of the reasons many people give up on doing good. The same way a normal mango plant cannot mature and bear fruit overnight, but a single celled plant can do that in minutes. That same way the rewards for doing good are staggered. Some can come almost instantaneously, some will not even come in your generation, but in your children's generation. But one thing is sure... It will come.
Another point here is that the more difficult the deed the more the blessing; it is more rewarding to be respectful to a mean boss than to be respectful to a nice boss, of course all depending on the circumstances.
But there are times when it feels like in return for the good you do all you get is evil... Well there are many explanation for that and that is a subject I've already talked on. It may be a test, an inheritance, or well, a reward for your previous wrongs.
Another point I want to add here is that currently, the world is structured to make things difficult for the good guys, but the bad guys have it relatively easy. Don't be afraid, it just means that you will be getting significantly better rewards for every good thing you do.
In conclusion, the ultimate decider of the morality of an action is God the creator, the one who knows all, of God says it is good, even if it breaks the laws of the international community, it is good. If God is on our side, who can stand against us. Seek God first before every action, it may seem like a waste of time, but in the long run the benefits are invaluable...
Okay brethren, remain faithful in Christ, love all, even as Christ loved the world. It may take some work, but we will certainly achieve Christ's standard.
Peace...

This is not sound Christian doctrine. You cannot earn anything from God. Grace is sufficient according to the Word of God. Please don't lead people astray by telling them they will get "rewards" from being kinder to those who abuse them. Clarify what you are trying to say.
