Is there a direct proportionality in the reward a person is likely to receive in Heaven vis-à-vis the good deeds he/she does on earth?

We see Jesus telling the 12 disciples who are sent out to preach, in Matt 10:40-41 (NRSVCE): > Whoever welcomes you welcomes me, and whoever welcomes me welcomes the one who sent me. Whoever welcomes a prophet in the name of a prophet will receive a prophet’s reward; and whoever welcomes a righteous person in the name of a righteous person will receive the reward of the righteous; But elsewhere, we see Jesus leaving it to God's grace in deciding how each one should be rewarded in Heaven, through the analogy of laborers in the vineyard (Matt 20:14-16): > "Take what belongs to you and go; I choose to give to this last the same as I give to you. Am I not allowed to do what I choose with what belongs to me? Or are you envious because I am generous? So the last will be first, and the first will be last." Reading Matt 10 and Matt 20 together, one doubts if a person entering Heaven "reaps as he sows" (Gal 6:7) or is permitted to "reap what others had sown" (Jn 4:38). My question, therefore, is: According to Catholic scholars, is there a direct proportionality in the reward a person is likely to receive in Heaven vis-à-vis the good deeds he/she does on earth?
