Even Paul say to obey.
Colossians 3:23 Whatever you do,
work at it with all your heart,
as working for the Lord, not for human masters, 24 since you know that
you will receive an inheritance from the Lord as a reward. It is the Lord Christ you are serving. 25 Anyone who does wrong will be repaid for their wrongs, and there is no favoritism.
Romans 2:5 But because of your stubbornness and your unrepentant heart, you are storing up wrath against yourself for the day of God’s wrath, when his righteous judgment will be revealed. 6
God “will repay each person according to what they have done.” 7
To those who by persistence in doing good seek glory, honor and immortality, he will give eternal life.
