God will ask, "I gave you the gift of grace, did you use it to follow my commandments?"
God will not reward those who take his gift of salvation and sit on it instead of using it.
Both Grace and sin require human cooperation. Unlike Grace, sin can be cooperated with by doing nothing.
"For the Son of Man is going to come in his Fathers glory with his angels, and then he will reward each person according to what they have done." - Matthew 16:24
Once again we have a RC who apparently has not read Ephesians 1 and 2. Grace is a free gift, given according to God’s discretion.
Grace is not earned nor merited or it would not be a free gift. It would be recompense and God would owe you salvation. And God is beholden to no one.
Read Ephesians and Romans. RCs struggle all day long to earn what God gives freely. RCs are not being told the truth. Read the bible for yourself.
