There's a reward for being a good worker
Colossians 3:24
Knowing that of the Lord ye shall receive the reward of the inheritance: for ye serve the Lord Christ.
Here on earth there are rewards for jobs well done. Good workers or people who do their best in whatever they are given to do are rewarded one way or the other. The rewards could be in form of gits, awards, money, praise, honour, medals, etc. Though believer work for men here on earth. Paul says that they are really working for Jesus, He says they should remember that it is Jesus who is going to pay them. This means that they will receive their rewards from Him Paul said categorically that Jesus would give the workers his full portion of all He owns. The rewards that Jesus will five are heavenly rewards.

Beloved, remember that just like a servant gets rewarded for the work that he does, we too should expect rewards from God. Nevertheless, the servants gets the rewards that could fade away. Earthly rewards, however, the reward that God Almighty will give us is eternal and can never fade.
That's how everything we do for God already has its reward.
