I do not have a religion, but I study different religions, so here’s my perception!
Accountability is important for Christian’s, because being dishonest is a big sin stated in the Bible, if you don’t take accountability for your actions as a Christian, that is considered lying or being dishonest meaning you would disappoint Jesus. I think taking accountability, for good or bad actions, is very important in life in general, not just for Christian’s.
Accountability is very important in my walk as a Christian because honestly you can not be a true Christian without it. When you hold yourself or even other accountable it helps you not make those same mistakes or sins again, and when you do not hold yourself or others accountable it can cause you to commit those same sins that you can avoid.
