2 Corinthians 5:14-15
14 For the love of Christ constraineth us; because we thus judge, that if one died for all, then were all dead:
15 And that he died for all, that they which live should not henceforth live unto themselves, but unto him which died for them, and rose again.
-Two related and often debated topics in Christianity are the ideas of eternal security and the freedom to sin after salvation. First off, the Bible teaches that “the law of the Spirit of life in Christ Jesus hath made [us] free from the law of sin and death.” (Romans 8:2) Eternal security is a sure thing because those who have been saved are no longer subject to sin and death. Establishing that brings us to the second topic; could not those who are saved live their lives any way they wish and not have anything to worry about? From that perspective, yes; but that way of thinking ignores the fact that when the Lord redeems us, He buys us and we belong to Him (1 Corinthians 6:19-20). We can’t live Godly to earn our salvation and we can’t live Godly to keep our salvation; but since Jesus Christ died the death that we should have died, we are constrained to live for Him.
