True repentance of sins shows in your actions.
If you are trying to stop or have stopped your sins, that shows a true repentance and is biblical.
what's with the trying....
Romans 6:14
For sin shall not have dominion over you: for ye are not under the law, but under grace.
Jesus defeated sin by giving us a way to be forgiven of it, and reconciled to God. We have to repent and turn from those sins, and be baptized for that forgiveness. Future sins still count against us unless we ask forgiveness of them to when they happen. The two scriptures I gave from Hebrews clearly shows that those people are partakers in Christ, and have received the Holy Spirit yet still turned back to willful sin.
agreed
Plus does Jesus teach we are saved immediately, or does He say we are saved after we have endured to the end ?
Lets see what He said;
if you have not been saved immediately....then you are enduring in an unsaved state...you were saved..you are being saved....you will be saved if you endure...
Matthew 24:10-13
And then many will fall away and betray one another and hate one another. And many false prophets will arise and lead many astray. And because lawlessness will be increased, the love of many will grow cold. But the one who endures to the end will be saved.
Matthew 10:22
And you will be hated by all for my name's sake. But the one who endures to the end will be saved.
Mark 13:9-13
“But be on your guard. For they will deliver you over to councils, and you will be beaten in synagogues, and you will stand before governors and kings for my sake, to bear witness before them. And the gospel must first be proclaimed to all nations. And when they bring you to trial and deliver you over, do not be anxious beforehand what you are to say, but say whatever is given you in that hour, for it is not you who speak, but the Holy Spirit. And brother will deliver brother over to death, and the father his child, and children will rise against parents and have them put to death. And you will be hated by all for my name's sake. But the one who endures to the end will be saved.
If it applies to the Apostles/disciples before us, and applies to believers after us, then it applies to us as well.
a man must first be saved to endure to the end.....to receive eternal life...
2 Timothy 1:9
Who hath saved us, and called us with an holy calling, not according to our works, but according to his own purpose and grace, which was given us in Christ Jesus before the world began,
Titus 3:5
Not by works of righteousness which we have done, but according to his mercy he saved us, by the washing of regeneration, and renewing of the Holy Ghost;
