Is God's grace limited or can we keep repenting? Can.God forgive the same sin 100 times after knowing the truth and it's a sin?
Notice that Jesus is not on record between his birth and death as speaking about grace. That's very significant.
Grace is very limited as to receives grace. Jesus was full of grace all his life, yet never taught about it.
John 1:16-17 (KJV)
[SUP]16 [/SUP] And of his fulness have all we received, and grace for grace.
[SUP]17 [/SUP] For the law was given by Moses, but grace and truth came by Jesus Christ.
All who are "in Christ" have the fulness of God's grace, while there are many conditions that determine whether a person is in him, or not, primarily requiring faith as Jesus taught. God has given grace before Jesus was born, before the law of Moses, such as toward Noah (his immediate family directly benefiting) to the exclusion of the rest of the world's population. That demonstrates that God limits who receives grace.
The gospel Jesus taught, and his disciples taught, requires repentance, followed by belief in Jesus and his gospel message, and following him all your days. While following, one walks in total grace of God, which assures many benefits. The benefits are all of the gospel, spanning from our simple need of a meal to eternal life, and all in between.
To repent is to forsake any sin that you become aware of through reading the word of God, by preaching gospel truth, or by conviction of the Spirit. Retaining habitual sin violates the gospel, subject to eternal death. God knows when a person goes too far, but sinners eventually realize their rebellion too. Neither God nor sinner will be surprised as to one's eternal condition at death. Each of us that have been made aware knows day to day where we stand with the Lord.
