There are five consequences of sinning in the Bible. Correspondingly there are five kinds of forgiveness.
Unless readers are aware of these differences they will be confused.
The consequence of sin determines the kind of forgiveness involved.
First here are the five consquences of sin in the Bible:
1.) Eternal perdition
2.) Separation from the people of God. For example in the Old Testament, a sinning Israelite might be cut off from the congregation and people of Israel. And in the New Testament, concerning a certain sinning Christian it was said "Remove the evil man from among yourselveds" (1 Cor. 5:13)
3.) Fellowship with God is hindered.
4.) If the sin is not put away, God will chasten and discipline.
5.) If the sin is not forsaken, Christ may deal with it when He comes to reign in the millennial kingdom. In that case the person's position in the millennial kingdom may be affected
There is a difference between consequence # 4 and # 5. The fourth consequence is chastizement in the church age, this current age. The fifth consequence results in chastisement in the coming age, after the second coming of Christ.
This statement in the Bible indicates that certain sins are forgiven in this age and certain sins are forgiven in the coming age:
" ... it will not be forgiven him, neither in this age nor in the one to come." (Matt:12:32b)
The implication is that some sins will be forgiven in the age to come after the second coming of Jesus Christ.
Now I will elaborate on the five kinds of forgiveness related to these five kinds of consequences of sin.
