If you are seeking the approval of men then why do you think you will be rewarded in heaven? Did you not already receive what you were seeking?

If you allow God to work through you and it is for His glory then you will be rewarded. Whatever you do, do for the Lord. For His glory, not your own.

John 12:42-43
Nevertheless many, even of the rulers, believed in Him, but because of the Pharisees they were not confessing Him, so that they would not be excommunicated from the synagogue; for they loved the approval of people rather than the approval of God.

Matthew 6:1-2
 “Take care not to practice your righteousness in the sight of people, to be noticed by them; otherwise you have no reward with your Father who is in heaven. “So when you give to the poor, do not sound a trumpet before you, as the hypocrites do in the synagogues and on the streets, so that they will be praised by people. Truly I say to you, they have their reward in full.

Colossians 3:23-24
Whatever you do, do your work heartily, as for the Lord and not for people, knowing that it is from the Lord that you will receive the reward of the inheritance. It is the Lord Christ whom you serve.
