8 Therefore do not be ashamed of the testimony of our Lord or of me His prisoner, but join with me in suffering for the gospel according to the power of God, 9 who has saved us and called us with a holy calling, not according to our works, but according to His own purpose and grace which was granted us in Christ Jesus from all eternity, 10 but now has been revealed by the appearing of our Savior Christ Jesus, who abolished death and brought life and immortality to light through the gospel, 11 for which I was appointed a preacher and an apostle and a teacher. 12 For this reason I also suffer these things, but I am not ashamed; for I know whom I have believed and I am convinced that He is able to guard what I have entrusted to Him until that day. 2 Timothy 1:8-12 (NASB)
There are some who believe that Romans 7:7-25 was written by the Apostle Paul in reference to before his salvation in that he proclaims his frustration with his inability to keep the law by his own strength….
However, the unregenerate are not able to see that only 100% obedience to the law is acceptable to God. In this, they do not have the same grief over their inconsistencies in obedience that a genuine believer has. On the other hand, there are some who teach a false doctrine of perfection for Christians. This doctrine teaches that it is possible for Christians to mature to the point that they no longer sin. This is why I hold that Romans 7:7-25 very clearly teaches us that if we attempt to keep the law through morality or legalism then we will experience that same frustration that Paul did. On the other hand, when we understand that it is not us who have overcome the world, but our Lord, then we will have a very different view of tribulation and peace in this life for Christians.
