How do Christians receive rewards for their works?

According to Paul, any reward received by Christians is ultimately due to the grace of God at work within them. He teaches that neither he who plants nor he who waters is anything, but it is God who gives the increase (1 Corinthians 3:7). Therefore, the rewards are not a matter of personal achievement but a reflection of God's grace working through us. This understanding allows believers to serve out of love and obedience rather than out of a desire for reward, reinforcing the notion that all glory and honor ultimately belong to God.
