Repenting is to feel bad for what you have done and ask forgiveness. Once you sincerely repent, it means that you try your best to stay away from that sin, not that you might not fall short sometimes, but every time you do, you feel bad about it and repent and ask forgiveness. True, sincere repentance through Jesus Christ is necessary for salvation.
If someone’s life is based around a particular sin, with no changes being made to correct it, it is hard to say that that person is truly repentant or sincere. If someone is happy about that sin, and brags about it or celebrates it, it is also hard to say that person is truly repentant. That would mean they are celebrating making God angry and disobeying Him. Not smart, especially for a Christian.
You can’t really support and celebrate something that is against God and be a Christian–that is being two-faced. God knows how you feel about it; you can’t hide it. Do you support God? Or do you support whatever makes you happy?
*[[Gal 1:9-10/KJV]]*
(9) As we said before, so say I now again, If any man preach any other gospel unto you than that ye have received, let him be accursed.
(10) For do I now persuade men, or God? or do I seek to please men? for if I yet pleased men, I should not be the servant of Christ.
Please strongly consider whether you are truly doing the things that demonstrate you are a Christian, or whether the things you are doing and the way you live show that you put the world and your desires first. Everyone falls short, and everyone can be forgiven, but not everyone cares enough to truly repent, even within the body of professed Christians.
God Bless
